The hypothesis that human fetuses are capable of perceiving pain during the first trimester has little evidence, although fetuses at 14 weeks may respond to touch.

The first ten weeks of gestational age is the period of embryogenesis and together with the first three weeks of prenatal development make up the first trimester of pregnancy. From the 10th week of gestation (8th week of development), the developing embryo is called a fetus.
At one time babies born in hospitals were removed from their mothers shortly after birth and brought to the mother only at feeding times. [67] Mothers were told that their newborns would be safer in the nursery and that the separation would offer the mothers more time to rest.

Hypercoagulability in pregnancy likely evolved to protect women from hemorrhage at the time of miscarriage or childbirth. In developing countries, the leading cause of maternal death is still hemorrhage. [25] In the United States 2011-2013, hemorrhage made up of 11.4% and pulmonary embolisms made up of 9.2% of all pregnancy-related deaths. [26]
