Q: What is a miscarriage and how common are they?
A: A miscarriage is the spontaneous loss of a pregnancy before 23-24 weeks of a pregnancy before the fetus becomes viable. The medical term for miscarriage is a "spontaneous abortion." Studies have shown that a miscarriage happens in about 60% of all pregnancies, and most of these happen before the pregnancy is clinically recognized. After a pregnancy is clinically recognized about 25% of pregnancies end in a miscarriage.
