Chances of Miscarriage After Normal Pregnancy

Updated June 16, 2014

Almost every pregnant women worries about miscarriage, at least in the beginning. This is understandable considering the scary statistics floating around out there that between 15% and 30% of confirmed pregnancies end in miscarriage, plus the even scarier statistic that claims 70% to 75% of conceptions end in miscarriage.

But if you have one or more living children, you may not need to worry quite that much, claims a 1989 study. British researchers examined the effects of women's previous pregnancy history on the risk of miscarriage in the next pregnancy, and they found that in women whose previous pregnancy had ended in a live birth, the risk of miscarriage the next time around was only 5% (1 in 20). With all previous pregnancies having ended in live birth, the risk was even lower still at 4% (1 in 25).

Obviously the risk of miscarriage will never be zero. But in this age of what is often too much information, it can be nice to know when you fall in a lower risk group.
