My Ultrasound Showed No Fetal Pole. Am I Miscarrying?
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.

No Fetal Heartbeat on Early Ultrasound. Is There Hope?
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.

My Ultrasound Showed No Gestational Sac. What Does That Mean?
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.
