Miscarriage / Pregnancy Loss: Most Popular Articles

These articles are the most popular over the last month.
Signs of Miscarriage
Worried about miscarriage? Learn the signs and symptoms that may indicate pregnancy loss. If you experience vaginal bleeding or pain in your lower abdomen, or if you're in the second or third trimester and you are not feeling your baby move, be sure to call your doctor.
Early Miscarriage Signs
In early pregnancy, miscarriage symptoms would generally include spotting, vaginal bleeding, and possibly cramping. Doctors may call this a chemical pregnancy.
First Trimester Miscarriage
First-trimester miscarriage, sometimes called spontaneous abortion, is very common but also heartbreaking for most moms. It's normal to have a lot of questions about signs of miscarriage, diagnosis, miscarriage causes, treatment, and risk factors. Find out answers here.
Miscarriage and hCG Levels
In very early pregnancy, doctors may use serial quantitative hCG blood tests to compare levels of hCG over two to three days. This is a common means of investigating miscarriage symptoms to check whether or not a pregnancy is viable.
Chemical Pregnancy
Despite the name, a chemical pregnancy is not a false pregnancy or a false positive on a pregnancy test -- it is a very early miscarriage. Doctors believe chemical pregnancies are usually caused by chromosomal abnormalities.
Normal hCG Levels
It's hard to pinpoint a normal hCG level at any point in pregnancy, since what is normal varies by the person and the situation. Two hCG levels taken over two to three days will provide more useful information in terms of miscarriage symptoms than a single measurement.
Did I Have a Miscarriage?
Signs and symptoms of miscarriage are rarely definitive, especially for first-trimester miscarriage, and it is not always easy to tell for sure if you have had a miscarriage. Learn how to interpret your signs and symptoms, and find out what tests your doctor might use.
D&C for Miscarriage
A D&C, or dilation and curettage, is a treatment for diagnosed miscarriages in the first trimester. The surgery clears the uterus and ends the physical part of miscarriage, shortening bleeding times and avoiding a potentially long wait for miscarriage bleeding to begin.
What Causes Miscarriages?
Miscarriage causes are not well understood by the medical community, but if you have had a recent loss, you are probably curious what may have caused it. Read a short overview of the most common known and suspected factors that contribute to miscarriage and pregnancy loss.
FAQs on hCG Levels
In early pregnancy, doctors often use serial tests of the pregnancy hormone hCG to gather clues about how the pregnancy is progressing. Sometimes, checking whether or not the hCG level is going up or down can provide information about whether or not a woman will miscarry, especially if she has miscarriage symptoms. But if you're not a doctor, early pregnancy hCG levels can be confusing.
H1N1 Vaccine
Public health agencies are strongly advising pregnant women to get the H1N1 swine flu vaccine, and you're not alone if you are concerned about exposure to any kind of drug or vaccine during pregnancy. Here's what you need to know about H1N1 swine flu vaccines and risk of miscarriage.
Implantation Bleeding
Light vaginal bleeding, or spotting, in early pregnancy may be due to implantation bleeding and may not necessarily be a sign of miscarriage. Learn what implantation bleeding looks like, when it occurs and how to distinguish implantation bleeding from an early miscarriage.
Premature Birth and Viability
Most sources define the point of viability in pregnancy as being around 24 weeks. This is the point at which a baby has a decent chance of survival if born prematurely. Other factors, such as birth weight and treatment with steroids before birth, can also affect whether or not a premature baby survives.
Miscarriage After Heartbeat
The risk of miscarriage drops after a doctor is able to detect the baby's heartbeat on an ultrasound, but the amount of decreased risk depends on other risk factors. Find out the different statistics for pregnancy loss after seeing a heartbeat.
Bleeding in Early Pregnancy
Spotting or bleeding in early pregnancy can be a symptom of miscarriage, but it does not always mean pregnancy loss. Call your doctor when concerned about possible signs of an early miscarriage.
Bicornuate Uterus
A bicornuate, or heart-shaped, uterus is one type of congenital uterine malformation that can be associated with pregnancy loss, although not usually first-trimester miscarriages. Septate uteri are frequently misdiagnosed as bicornuate uteri.
Miscarriage Diagnosis Tools
Worried about miscarriage? If you are experiencing vaginal bleeding or other miscarriage symptoms, learn about the tests doctors use to diagnose pregnancy losses, such as hCG doubling times, transvaginal ultrasounds, and fetal heart rate monitoring.
Basic Miscarriage Statistics
The vast majority of miscarriages happen in early pregnancy. The statistics suggest that the risk of pregnancy loss goes down significantly after 12 weeks. Seeing a heartbeat on an ultrasound also puts the pregnancy into a lower risk category.
Understanding Blighted Ovum
A blighted ovum is a miscarriage in which the baby does not develop, but a gestational sac continues to grow and the woman may continue to experience pregnancy symptoms. A blighted ovum can be a missed miscarriage treated via D & C or may end naturally.
Low hCG Levels
Doctors often check levels of hCG, a pregnancy hormone, to investigate miscarriage symptoms in early pregnancy. Low levels of hCG in two consecutive hCG blood tests can be a cause for concern, but a single low level does not give much information on whether or not the pregnancy is viable.
Ectopic Pregnancy
Ectopic pregnancies, sometimes called tubal pregnancies, happen when a fertilized egg implants someplace other than in the uterus, such as the fallopian tubes. Symptoms of ectopic pregnancy include severe abdominal cramping and dizziness.
Early Pregnancy Ultrasound
When early ultrasound results aren't reassuring, such as when an ultrasound shows no fetal heartbeat or an empty gestational sac, the doctor may be able to diagnose miscarriage if other information is available -- but the results could simply mean that the dating of the pregnancy is incorrect. When in doubt, the doctor will order another ultrasound.
Miscarriage Management Options
After diagnosing a miscarriage, your doctor may ask whether you want a D&C or whether you want to wait for the miscarriage to happen naturally. You may also have the option of taking medication to speed up the process. Each pregnancy loss treatment choice has pros and cons, and different women have different preferences.
Second Trimester Miscarriages
Late miscarriages, such as those in the second trimester, can happen for a number of reasons. Causes might be chromosomal abnormalities, cervical insufficiency, congenital birth defects, placental problems, or other factors.
Missed Miscarriage
A missed miscarriage is a pregnancy loss, usually in the first trimester, in which the doctor diagnoses the miscarriage based on lab results or other clinical evidence but the woman has not have definite miscarriage symptoms.
Cramping in Early Pregnancy
Many women worry about cramping during pregnancy. Although early pregnancy cramps can occur in a miscarriage, mild cramping on its own is not necessarily a sign or symptom of miscarriage. Severe abdominal cramping, however, can be an ectopic pregnancy symptom. Cramping accompanied by vaginal bleeding is more likely to mean a miscarriage.
Loss of Pregnancy Symptoms
Pregnancy symptoms can fade, fluctuate, or disappear entirely even in a normal pregnancy -- so loss of pregnancy symptoms of disappearing morning sickness is not necessarily a miscarriage symptom.
Normal hCG Doubling Times
Doctors sometimes check the hCG doubling times for patients worried about miscarriage symptoms, such as bleeding during pregnancy in the early weeks. If the hCG doubles every two to three days, that is a reassuring sign that the pregnancy may be viable.
Baby Not Kicking
In the third trimester, sudden reduction of fetal movement can be an early warning sign of a problem. Learn how kick counts can help you screen for changes in your baby's movement patterns.
False Negative Pregnancy Test
False negative pregnancy tests are a definite possibility if you are trying to test before your menstrual period is due, but by the time your period is late, a pregnancy test should show a positive if you are pregnant. Getting a negative pregnancy test after having had a positive could be a sign of early miscarriage.
When hCG Levels Drop
Drops in hCG levels in early pregnancy and during the first trimester are usually not a good sign; this can be a sign of impending miscarriage. In rare cases, hCG levels might fluctuate because of a condition called vanishing twin syndrome.
No Fetal Pole
The fetal pole is the early developing baby when it first becomes visible in the uterus on an ultrasound. Usually an ultrasound will pick up the fetal pole by 5 to 6 weeks gestational age. If there's an empty gestational sac, it might be a miscarriage but might also be the pregnancy is just not far enough along to see the fetal pole.
Miscarriage Process
By the time miscarriage symptoms appear, what is happening in the body during a miscarriage is that the body has recognized a nonviable pregnancy and begun shedding the uterine lining. In the majority of cases, the baby's heartbeat has already stopped before the physical process begins.
Miscarriage Symptoms
Spotting or bleeding in early pregnancy is often the first sign of a miscarriage, but there may also be other signs of an impending miscarriage, such as falling hCG levels.
What Spotting Looks Like
Spotting is a lay term for light vaginal bleeding during pregnancy. Pregnancy spotting that is light in quantity and color is more likely to mean implantation bleeding or other non-worrisome causes, whereas bleeding that is heavier and like a menstrual period, is more likely to be miscarriage bleeding.
Progesterone
Progesterone supplements are often used to treat women who have low progesterone levels and who have a history of recurrent miscarriages, but the supplements are the subject of controversy. Learn why some doctors prescribe progesterone for recurrent miscarriages and others do not.
MTHFR Genes and Miscarriage
MTHFR gene mutations can increase the risk of high homocysteine and might increase the risk of blood clots. Some doctors test for and treat common MTHFR gene variants as a risk factor for recurrent miscarriages, while others consider MTHFR tests worthless in treating miscarriages. What gives?
Slow Rising hCG Levels
Slow-rising hCG levels can be a sign of problems, such as impending miscarriage or a symptom of ectopic pregnancy, but as many as 15% of normal pregnancies may begin with slow-rising hCG levels. Stay in touch with your doctor if you are concerned about slow-rising hCG levels.
Bleeding After Miscarriage
The number of days of vaginal bleeding after a miscarriage varies for each woman, but it should stop within about two weeks of the pregnancy loss in most cases.
Sex After Miscarriage
Doctors usually advise abstaining from sexual activity for one to two weeks following a miscarriage because of increased chances of gynecological infections during the miscarriage bleeding. Be sure to consider contraception if you do not want to get pregnant again immediately.
Baby Aspirin and Miscarriages
Baby aspirin, or low-dose aspirin, is a possible treatment of recurrent miscarriages. Right now, there is evidence that using baby aspirin in pregnancy helps women with blood clotting disorders when used along with heparin. Researchers are investigating whether it might help women without diagnosed thrombophilia disorders.
Natural Miscarriage
When miscarriage does not involve a medical emergency, women sometimes can choose which type of medical management they prefer, and some women prefer to let nature take its course and miscarry without any type of intervention. Choosing this approach has definite pros and cons.
Ultrasound for Miscarriage
Ultrasounds are a common test for suspected pregnancy loss or threatened miscarriage. By using an ultrasound, a doctor can get an image of the gestational sac and the developing baby's heartbeat in order to determine whether or not the pregnancy is viable.
Gestational Sac on Ultrasound
Find out when the gestational sac is supposed to become visible on an early pregnancy ultrasound.
Subchorionic Hematoma
Bleeding during pregnancy can be a sign of miscarriage but another possible explanation is a subchorionic hematoma, a type of bleeding between the placenta and the wall of the uterus. A pregnancy with a subchorionic hematoma faces an increased risk of miscarriage but can also go on to be viable.
Misoprostol for Miscarriage
Medication can be an alternative to D&C for managing a missed or incomplete miscarriage when the woman prefers not to wait for a natural miscarriage.
Quantitative hCG Blood Test
Quantitative hCG blood tests are the most common means of investigating signs of early miscarriage; women who have bleeding during the first few weeks of pregnancy often have serial blood tests to check hCG doubling times in order to gauge the odds of miscarriage.
Normal Fetal Heart Rate
The normal fetal heart rate can vary by the point in the pregnancy. When ultrasound detects a slow fetal heart rate, this may mean higher risk of miscarriage, but a rapid fetal heart rate does not increase the odds of miscarriage or other pregnancy complications.
Pregnancy Test Still Positive
It can take some time for your hCG levels to return to zero after you have had a miscarriage, so it is normal if you are still getting a positive pregnancy test in the first week or two following your miscarriage.
Lighter Line on Pregnancy Test
Analyzing the color of the line on a home pregnancy test is not a reliable way to determine whether or not you are miscarrying. Taking two consecutive home pregnancy tests to check the color will not tell you whether your hCG is rising appropriately.
Stillbirth Causes and Coping
If you have had a stillbirth, or if you are trying to support someone through a stillbirth, this article contains answers to the most common questions about why stillbirths happen and issues that arise in the aftermath of having a stillborn baby.
Physical Recovery
Recovery from a miscarriage or stillbirth will be different depending on the point in pregnancy when the pregnancy loss occurred and whether or not you had a D&C. In all losses, you will probably be advised to avoid sexual intercourse and tampons for at least two weeks and you will need a RhoGAM shot if you are Rh negative.
No Fetal Heartbeat
Naturally it is quite scary to be told your baby has no heartbeat. But on an early ultrasound, it can be normal to see no fetal heartbeat, although it can also be a sign of missed miscarriage or blighted ovum.
Ultrasound and Miscarriage
Ultrasound results in early pregnancy can be confusing -- sometimes it is not clear whether the results mean a blighted ovum or missed miscarriage or simply early stages of a normal pregnancy. Learn what one medical body uses as criteria for diagnosing miscarriage from an ultrasound.
Slow Fetal Heart Rate
A slow heart rate in a developing baby is cause for concern, but it's impossible to tell without waiting for a followup ultrasound whether the pregnancy will end in miscarriage or continue to term.
Miscarriage Risk Factor Stats
Many miscarriage statistics focus on women overall, but certain groups face higher risk of miscarriage than others because of pre-existing risk factors. Find out the rates of pregnancy loss for specific groups.
Infection After Miscarriage
Whether women choose D & C, natural miscarriage, or medically expedited management after receiving a miscarriage diagnosis, there is a small chance that retained tissue in the uterus could lead to an infection. Learn the symptoms of a post-miscarriage infection.
Signs of Ectopic Pregnancy
Early symptoms of tubal pregnancy might be mild cramping in the lower abdomen or spotting in early pregnancy. Women should call their doctors if concerned. Anyone having symptoms of a possible ruptured ectopic pregnancy should head for the emergency room.
Immediate Pregnancy After Loss
Doctors often advise waiting to get pregnant again after miscarriage, but is the wait really necessary? Will an immediate subsequent pregnancy increase the risk for another miscarriage?
Recurrent Miscarriage Causes
Recurrent miscarriages may have a variety of causes, ranging from anatomical/uterine problems to autoimmune disorders to hormonal imbalances. The medical community does not always agree on some theorized miscarriage causes. This article offers an overview of the different factors thought to play a role in recurrent pregnancy loss.
Spotting
Women often use the term "spotting" to refer to very light vaginal bleeding in pregnancy or between periods. Spotting can be a first symptom of impending miscarriage but can occur for other reasons as well.
Miscarriage and Rh Status
Women who are Rh negative often wonder if they need Rh immune globulin, such as RhoGAM, after having first-trimester miscarriages or ectopic pregnancies. Most doctors recommend RhoGAM shots to women after miscarriage because of theoretical risk of Rh sensitization.
Why Genes Cause Miscarriage
Miscarriages are usually blamed on chromosomal abnormalities, but why exactly do problems in the chromosomes lead to miscarriage in some cases while babies can be born with chromosomal disorders in other cases? Researchers aren't 100% sure.
Miscarriage Risk Factors
Miscarriages are usually no one's fault, but this overview article covers a few risk factors that are statistically correlated with higher rates of pregnancy loss, as well as a few more factors may or may not be associated with increased risk.
Early Miscarriage
Signs and symptoms of an early miscarriage would include bleeding after a positive pregnancy test, cramping, and possibly loss of pregnancy symptoms. Find out what to do if you think you are having an early miscarriage.
Miscarriages and the ER
Miscarriage symptoms, such as vaginal bleeding or spotting in early pregnancy, often send women to the emergency room. Sadly, however, emergency room doctors can almost never do anything to stop a miscarriage that's in progress.
Birth Control and Miscarriage
There is conflicting research on whether long-term use of oral contraceptives increases the risk of miscarriage in a future pregnancy. Researchers do not yet know the answer. Pregnancies accidentally conceived while on birth control do not seem at increased risk.
Find Your Miscarriage Risk
Many women wonder when the odds of miscarriage go down, but the truth is that there isn't one single answer for all women. Miscarriage statistics vary by groups and factors. Figure out your miscarriage risk with these steps.
Inducing a Miscarriage
If you are searching for information on how to cause a miscarriage, force a miscarriage, or induce a miscarriage, please read this first and be sure to keep your safety in mind.
Yolk Sac
The yolk sac is the first thing that becomes visible inside the gestational sac in early pregnancy on an ultrasound. It is an early structure that helps to nourish the developing fetal pole until the circulatory system is developed and disappears as the embryo grows.
Gestational Sac
The gestational sac is where a baby develops in the uterus during pregnancy. The sac encloses the baby and amniotic fluid, and the placenta attaches the sac to the uterine lining.
Septate Uterus
Having a septate uterus is a risk factor for recurrent miscarriages and preterm birth, and many doctors believe that treatment of a uterine septum can improve odds of having a successful pregnancy.
Miscarriage Tissue
One particularly troubling aspect of having a miscarriage can be the experience of passing tissue or large blot clots during the associated vaginal bleeding. The miscarriage tissue may or may not be recognizable, depending on how far along the pregnancy was at the time of the miscarriage.
Return of Menstrual Period
Your menstrual period should return within six to eight weeks after a miscarriage. The exact time will vary based on the circumstances of the pregnancy loss.
Flu Vaccine in First Trimester
There are known risks to having the flu during pregnancy, but what about the flu vaccine? Existing evidence suggests influenza vaccination is safe during pregnancy but research is limited on the first trimester.
High hCG Levels
Many women worry about higher or lower than average hCG levels, but individual levels usually don't mean anything. Having a trend toward higher hCG levels can be normal or can be a sign of complications like molar pregnancy.
Incomplete Miscarriage
The term "incomplete miscarriage" means a miscarriage in which tissue remains in the uterus. Most miscarriages that are incomplete at the time of diagnosis will complete without intervention, but sometimes a D&C is needed to remove pregnancy tissue that is retained in the uterus.
When Can I Try Again?
After a miscarriage, many couples want to try to get pregnant again as soon as possible, but advice varies on the best amount of time to wait to try for a new pregnancy. Some doctors advise waiting as long as three months, whereas others say trying again immediately is OK.
Reasons for Miscarriage
It's not easy to identify the reason for a miscarriage. In many cases, the cause may never be found. Most first trimester miscarriages occur because of chromosomal abnormalities, but some may also occur due to infections, chronic health conditions, or unexplained reasons.
Still Have Pregnancy Symptoms
It can take some time for your hormone levels to return to normal following a miscarriage, so it is not uncommon to still feel pregnancy symptoms for a few weeks after a miscarriage.
Sex During Pregnancy
Most doctors agree that sexual intercourse during pregnancy is safe and not likely to be a risk factor for causing miscarriage in the vast majority of women.
Threatened Miscarriage
Doctors use the term threatened miscarriage for women who experience bleeding in pregnancy (or other miscarriage symptoms) but the cervix is still closed. In these cases, finding out whether or not the signs mean miscarriage might mean waiting a few days to a week for hCG or ultrasound test results.
No Yolk Sac
When an ultrasound shows no yolk sac inside the gestational sac, the pregnancy is either too early for the yolk sac to be seen or a miscarriage has occurred.
Rh- Mothers and Miscarriage
Rh negative women who suffer miscarriages often wonder whether their Rh status might have been responsible. Although Rh sensitization can cause problems later in pregnancy and can increase risk of stillbirth, Rh sensitization does not typically cause first-trimester miscarriages.
Cervical Insufficiency
Incompetent cervix is a medical condition in which the cervix dilates too early in the pregnancy, resulting in pregnancy loss or premature birth. Learn about the symptoms, causes, diagnosis procedures and future treatment to prevent miscarriage.
Reasons for Bleeding
Somewhere around 30% of all pregnant women have some sort of bleeding during pregnancy, most commonly in the first trimester. Although miscarriage is one possible explanation for first-trimester bleeding, it isn't the only possible reason.
Pregnancy Cramps
Early pregnancy cramps frequently occur in normal pregnancies and are usually not a sign of problems, but in some cases it's a good idea to call your doctor to be on the safe side.
Miscarriage Gifts
Looking for a good gift for someone who has had a miscarriage or stillbirth? Pregnancy loss cards, miscarriage jewelry, charitable donations, and planting a tree are all good ideas for how to offer show sympathy and honor your friend, coworker, or relative's baby.
Ovulation After Miscarriage
Unfortunately there is no way to predict when you will ovulate after a miscarriage except by using ovulation predictor strips. It could be anywhere from two weeks to three months after the miscarriage before your fertility returns.
Antiphospholipid Syndrome
Antiphospholipid antibodies may cause recurrent miscarriages in some women, but are rarely associated with any symptoms before that. The most common antibodies tested are lupus anticoagulant antibodies and anticardiolipin antibodies. Treatment with heparin and low-dose aspirin may improve pregnancy outcomes for women with recurrent miscarriages.
Pregnant After Miscarriage
Theoretically it may be possible to conceive and get pregnant again a mere two weeks after a miscarriage, but menstruation resumes at different types for different women. You should use contraception if you do not want to be pregnant again right away or if your doctor has advised you to wait.
Period During Pregnancy
Generally it is not possible to have a menstrual period during pregnancy, but bleeding during pregnancy can occur for a number of reasons and may have a similar appearance to a menstrual period.
Problems with the Uterus
Problems with the structure of the uterus can increase the risk for recurrent miscarriages and preterm delivery. A few of the most common culprits that contribute to pregnancy loss are septate uterus, fibroids, and polyps.
Alcohol and Miscarriage
Alcohol and pregnancy doesn't mix, and drinking during pregnancy can cause numerous problems. Occasionally drinking alcohol doesn't seem to be linked to miscarriage specifically. Regular alcohol intake may be linked with miscarriage risk.
Waiting for a Miscarriage
When doctors diagnose a miscarriage, it's impossible to say exactly how long it will take until the process is complete -- but for the majority of women, it will be over within two weeks after the diagnosis. A missed miscarriage or blighted ovum might take longer to miscarry.
Missed Miscarriage Symptoms
Most women do not have warning signs of a missed miscarriage -- and as a result the diagnosis can catch you off guard. Possible missed miscarriage symptoms can include loss of pregnancy symptoms or lack of a fetal heartbeat on ultrasound.
Viable Pregnancy
A pregnancy is said to be "viable" when there are no signs of miscarriage or impending pregnancy loss and the pregnancy can be expected to result in the birth of a live infant. If a doctor says a pregnancy is not viable, this means that pregnancy loss is inevitable, such as in an ectopic pregnancy.
No Gestational Sac
What does it mean when an early pregnancy ultrasound shows no gestational sac in the uterus? Possible explanations could be ectopic pregnancy, early miscarriage, or a normal pregnancy that is still in very early stages.
Recurrent Miscarriage Tests
Women who have had multiple miscarriages should see a doctor for testing for possible causes. About half the time, doctors can find a possibly treatable medical problem that may have caused the recurrent miscarriages.
Molar Pregnancy Overview
Molar pregnancy is a scary condition that causes pregnancy tissue to overgrow, and the fetus does not develop normally.
Stillbirth Causes
Women who experience a late miscarriage or stillbirth usually want to know why it happened, but stillbirth causes can be hard to pinpoint. There are some factors known to cause or increase risk of stillbirth, but most of these devastating losses are never explained.
Stress and Miscarriage
Stress during pregnancy is controversial as a potential risk factor for or cause of miscarriage. Some sources claim the link is a myth, but some research studies support that high stress or anxiety in the mother might be a cause of miscarriages.
Ultrasounds and Due Dates
Sometimes the due dates estimated by an early ultrasound don't match the expected due date based on the last menstrual period. This is usually not a sign of a problem with the pregnancy.
Lifestyle and Miscarriage Risk
Miscarriage is usually no one's fault, and even women with no miscarriage risk factors can have a pregnancy loss. However, studies have found that a few lifestyle factors can increase risk of pregnancy loss. Avoiding these risk factors can increase the odds of a successful pregnancy.
Coping with Pregnancy Loss
Miscarriage grief may feel overwhelming, especially in the initial aftermath of the pregnancy loss. You may face anxiety, anger, depression, or any number of feelings. You might find your relationship strained and you might feel reluctant to face the world. Specific coping tips may help you deal with your feelings about your miscarriage.
Infections and Miscarriage
Certain bacterial and viral infections can be linked to pregnancy loss. Sexually transmitted diseases such as chlamydia in pregnancy can increase the risk of ectopic pregnancy; other infections, such as parvovirus B19 (fifth disease), can be a miscarriage risk factor.
Fetal Pole
The medical term for the earliest signs of a baby in an early pregnancy ultrasound. With a transvaginal ultrasound, the fetal pole becomes visible around 6 weeks of gestation.
Smoking and Miscarriage
Smoking in pregnancy is one of the few miscarriage risk factors that is under your control. Evidence suggests that smoking and even exposure to secondhand smoke can increase the risk of miscarriage or stillbirth.
Ectopic hCG Levels
Research shows that slow-rising hCG levels that are not doubling every two to three days may mean a greater risk of ectopic pregnancy. But ectopic hCG levels are not always clear, and slow rising hCG can occur for other reasons.
Retroverted Uterus
About 20% of women have a retroverted uterus and it is almost never a factor in causing a miscarriage, although one rare condition can occur later in pregnancy if a tilted uterus does not correct on its own.
Cats and Miscarriage
Many women worry that their cats might cause a miscarriage by transmitting toxoplasmosis, an infection associated with miscarriage. But the risk many people associate with cats is usually overblown.
Intrauterine Fetal Demise
Intrauterine fetal demise is the clinical term for a baby that has died in the womb, leading to second-trimester miscarriage or stillbirth.
Miscarriage Misdiagnosis
Naturally most women want to be absolutely certain that it's really a miscarriage before making decisions about treatment. Most doctors are very careful about being totally certain before giving a diagnosis of miscarriage, but rarely, viable pregnancies may be misdiagnosed as miscarriage.
Deciding When to Try Again
Many people struggle with the question of when to try again after experiencing a miscarriage, stillbirth, or other pregnancy loss. Here are some questions to ask yourself in deciding when you are ready for a new pregnancy.
Fertility After Miscarriage
You may have heard that women are more fertile after an early miscarriage. You may have also heard that it's a myth that women have better fertility after miscarriage. What's the truth?
What to Say
After a miscarriage or pregnancy loss, your friend or relative needs your support. Learn what to say, what to avoid doing, and how you can give your friend or relative space if she needs to grieve the loss of her pregnancy.
Progesterone Cream
Multiple over-the-counter progesterone creams are sold in health food stores, and some people claim that these creams can prevent miscarriage or treat recurrent miscarriages. Before you try to use any of these progesterone creams, be sure to read up on the safety concerns (and the truth about wild yam cream and progesterone).
Morning Sickness Suddenly Gone
Although nausea and other pregnancy symptoms usually last until around the end of the first trimester, suddenly disappearing morning sickness or nausea is not necessarily a sign of miscarriage.
Risk in Next Pregnancy
After one miscarriage, the risk of having another miscarriage does not increase much -- but there's some evidence that there might be increased risk of other pregnancy complications, such as preterm birth.
Mothers Over 35
Miscarriage and stillbirth are more common in mothers older than 35 and even more so in moms over 40. But what causes the increased risk for pregnancy loss?
Chromosomal Abnormality Causes
According to research, random chromosomal abnormalities are the culprit in most miscarriages and in many stillbirths. But what causes the chromosomal abnormalities themselves? Parental age is one risk factor but evidence is mixed on others.
Miscarriage and Amniocentesis
An amniocentesis can be an important and informative prenatal test that can diagnose numerous conditions in the unborn baby, but many women fear the test because of the small increase in risk of miscarriage or pregnancy loss that can occur after the test.
Spotting FAQ
Spotting during pregnancy can be scary even though you may know it's not necessarily a sign of miscarriage. Get answers to common questions about light vaginal bleeding in the first trimester, such as what implantation bleeding looks like, possible causes of spotting and what to do if you are worried about miscarriage.
Normal Cramping
The amount of pain and lower abdominal cramping during a first trimester miscarriage tends to vary by how far along the pregnancy was when the miscarriage happened and other individual circumstances. Severe pain could by a symptom of ectopic pregnancy.
Causes of Spotting
Spotting, or light vaginal bleeding, in pregnancy can have numerous causes, only one of which is an impending miscarriage. Learn other possible reasons why you may experience spotting during pregnancy.
Vasa Previa
Vasa previa is a potentially devastating pregnancy complication in which fetal blood vessels grow across the cervix and can rupture during labor. Vasa previa may involve velamentous insertion of the umbilical cord and can develop in association with placenta previa. Undetected vasa previa can lead to stillbirth or infant loss.
Gestational Age
The gestational age of the pregnancy is technically the number of weeks since the mother's last menstrual period.
Heparin for Miscarriages
Heparin is a blood thinner that doctors often prescribe for women with recurrent miscarriages and a thrombophilia disorder such as antiphospholipid syndrome or lupus anticoagulant antibodies. The treatment improves pregnancy outcomes for women with antiphospholipid syndrome.
Emotional Aftermath
Miscarriage and pregnancy loss bring out different feelings for different people. Sadness can feel overwhelming at first but, over time, coping with miscarriage will get easier. Many women may go through the often-cited five stages of grief after a pregnancy loss.
Chromosomal Abnormality
The term chromosomal abnormality, as it pertains to miscarriage and pregnancy loss, means that a developing baby has an incorrect number of chromosomes or chromosomes with missing or extra pieces.
Fever and Miscarriage
Fever during pregnancy can increase the risk of neural tube defects, but right now there is little evidence that fever can cause first-trimester miscarriages.
No Morning Sickness
Studies have shown that women with morning sickness may be less likely to miscarry, but that doesn't mean that it's a bad sign if you don't have any nausea -- plenty of women never experience morning sickness in normal pregnancies.
Miscarriage Myths
There's a lot of confusing information about miscarriage causes and risk factors, and no one seems to quite agree on what's myth and what's truth. Here is your guide to the real story on various claims about what can and cannot cause a miscarriage.
Types of Pregnancy Loss
Pregnancy loss can happen for a number of reasons and generally falls into several categories, including miscarriage in the first or second trimester, ectopic pregnancy, molar pregnancy, missed miscarriage, blighted ovum, stillbirth, neonatal death, or medically indicated termination.
D&C and Preterm Birth Risk
Numerous studies have looked at whether or not D & C procedures might increase the risk for preterm birth in future pregnancies, but the jury is still out on whether having a D&C after a miscarriage increases risks.
Morning Sickness & Miscarriage
If you have heard that having nausea during pregnancy is a good sign, you're right. Studies show that women with morning sickness are less likely to have a miscarriage. But it's not a hard and fast rule; it's still possible to miscarry with morning sickness, and feeling no nausea is not a sign of miscarriage.
Unicornuate Uterus
Having a unicornuate uterus is similar to having a half of a normal uterus. Women with this congenital uterine abnormality face increased risk of miscarriage and preterm labor.
Balanced Translocations
Balanced translocation, also called reciprocal translocation, is a type of chromosomal abnormality that can cause recurrent miscarriages in some couples. Balanced translocation means that sections of two chromosomes have switched places.
Miscarriage Complications
Most of the time, a first-trimester miscarriage doesn't lead to serious long-term physical problems, but sometimes complications can arise.
Normal Miscarriage Bleeding
Normal bleeding after a miscarriage can sometimes be surprisingly heavy, but make sure that you seek medical attention if you have any suspicion you might be hemorrhaging.
Signs of Depression
The signs and symptoms of depression are not that different from the signs of typical grief after a pregnancy loss. Thus, when you are grieving a miscarriage or pregnancy loss, it can be hard to tell whether or not you have developed clinical depression.
hCG After Miscarriage
Your hCG level does not fall to zero immediately after a miscarriage; it can take some weeks to return to pre-pregnancy levels.
Unexplained Pregnancy Loss
More often than not, doctors have no clear answers for why a specific pregnancy loss happened. They know much about general miscarriage causes but can rarely pinpoint an explanation for individual miscarriages and stillbirths, and sometimes this can be hard to accept.
Treatment of Ectopic Pregnancy
An ectopic pregnancy diagnosis does not always require emergency surgery. If doctors detect the ectopic pregnancy early enough before it threatens to rupture the fallopian tube, a drug called methotrexate can be effective treatment.
Stomach Pains
Stomach pains, in the true sense of the word, are usually not a miscarriage symptom. The cramps associated with miscarriage are more likely to be centered in the lower abdomen or lower back. However, stomach pains should be mentioned to a doctor, and call a doctor right away if pains are severe, as ectopic pregnancy should be ruled out.
Cold or Flu During Pregnancy
A few types of viral and bacterial infections during pregnancy are linked to miscarriage, but should pregnant women worry about the common cold or the flu? The two infections have never been definitively linked to miscarriage but they might cause other complications.
Exercise and Miscarriages
Most sources claim that exercise does not cause miscarriage and pregnancy loss, but the relationship is unclear. One large scale retrospective study did find a link between high-impact/strenuous exercise and miscarriages.
Diagnosing Ectopic Pregnancy
It's not always obvious when a pregnancy is ectopic, and many people do not have symptoms until the tubal pregnancy has become an emergency. Here is how doctors determine whether a pregnancy is ectopic.
Miscarriage Diagnosis
