Before killing an unborn child, the abortionist must first determine how long the baby's mom has been pregnant. Only by determining how long the baby has been alive can the abortionist choose the most effective method to kill it.
Pregnancy is divided into three trimesters. The first trimester lasts through
the 12th week. The second trimester begins at week 13 and continues through
week 24. The third trimester is the remaining time until the baby is delivered.
For each trimester specific methods of abortion are used.
