Miscarriage is the spontaneous loss of a pregnancy before the 20th week. About 10 to 20 percent of known pregnancies end in miscarriage. But the actual number is likely higher because many miscarriages occur so early in pregnancy that a woman doesn't realize she's pregnant.
Miscarriage is a somewhat loaded term — possibly suggesting that something was amiss in the carrying of the pregnancy. This is rarely true. Most miscarriages occur because the fetus isn't developing normally.
Miscarriage is a relatively common experience — but that doesn't make it any easier. Take a step toward emotional healing by understanding what can cause a miscarriage, what increases the risk and what medical care might be needed.
