Death before birth
Death before birth can happen in several ways: stillbirth, when the fetus dies before or during the delivery process; miscarriage, when the embryo dies before independent survival; and abortion, the artificial termination of the pregnancy. Stillbirth and miscarriage can happen for various reasons, while abortion is carried out purposely.
Stillbirth
Stillbirth can happen right before or after the delivery of a fetus. It can result from defects of the fetus or risk factors present in the mother. Reductions of these factors, caesarean sections when risks are present, and early detection of birth defects have lowered the rate of stillbirth. However, 1% of births in the United States end in a stillbirth.[74]
Miscarriage
A miscarriage is defined by the World Health Organization as, "The expulsion or extraction from its mother of an embryo or fetus weighing 500g or less." Miscarriage is one of the most frequent problems in pregnancy, and is reported in around 12–15% of all clinical pregnancies; however, by including pregnancy losses during menstruation, it could be up to 17–22% of all pregnancies. There are many risk-factors involved in miscarriage; consumption of caffeine, tobacco, alcohol, drugs, having a previous miscarriage, and the use of abortion can increase the chances of having a miscarriage.[75]
Abortion
An abortion may be performed for many reasons, such as pregnancy from rape, financial constraints of having a child, teenage pregnancy, and the lack of support from a significant other.[76] There are two forms of abortion: a medical abortion and an in-clinic abortion or sometimes referred to as a surgical abortion. A medical abortion involves taking a pill that will terminate the pregnancy no more than 11 weeks past the last period, and an in-clinic abortion involves a medical procedure using suction to empty the uterus; this is possible after 12 weeks, but it may be more difficult to find an operating doctor who will go through with the procedure.
