The medical term for it is "abortion"; when the abortion is not deliberately induced, it is termed a "spontaneous abortion," so that is a synonym for "miscarriage." Miscarriages can occur for many reasons, not all of which can be identified. While miscarriage can result from physical trauma, like exposure to certain chemicals, diseases, or physical blows, they are rarely the cause. A miscarriage usually results from biological defects in the mother or genetic defects in the developing fetus.
Most such terminations occur very early in pregnancy, during the first trimester, and many people restrict the term "miscarriage" to terminations during the second trimester. Miscarriages frequently occur so early that the woman is not even aware that she is pregnant. Some women are prone to miscarry; the term "habitual abortion" describes the condition where three consecutive pregnancies have terminated before 20 weeks gestation.
In the past, a frequently used synonym for miscarriage, was to say that the mother "lost the baby". This phrase is not as popular in current times, because there is less of a cultural stigma on discussing issues related to reproduction, and because some people feel that it carries the connotation that the expectant mother was, somehow, at fault for the miscarriage.
