*'''[[Methotrexate]]''' is typically used as a treatment for autoimmune disorders and cancer by inhibiting the metabolism of folic acid, the B vitamin necessary for cell division. Methotrexate attacks the fast-growing cells called trophoblasts, which essentially are life support for the fetus. The trophoblasts draw oxygen and nutrients from the mother's blood supply.<ref name="life"></ref> Deprived of nutrition and oxygen, the baby dies.

==Legality==
In the United States, state governments can only restrict abortions after the first trimester.<ref name="court">[http://www.religioustolerance.org/abo_supr.htm Abortion Access, ReligiousTolerance.org]</ref> This means that a woman can freely decide to terminate her pregnancy in the first trimester, even if suffering no medical complications. In the Supreme Court case [[Roe v. Wade]], the Court found that:
{{cquote|For the stage prior to approximately the end of the first trimester, the abortion decision and its effectuation must be left to the medical judgment of the pregnant woman's attending physician.}}<ref name="court"></ref>
==Fetal development in the first trimester==
The following is a list of developmental traits acquired by the fetus in the first trimester of pregnancy.
*'''Heartbeat begins''' - the baby's heart first starts beating at around five weeks gestation, though the precursor to the [[circulatory system]] begin forming as early as three weeks.
*'''The brain''' begins to form its most complex parts.
*'''Arms, legs, hands, and feet''' are maturing. The baby can make a fist at around nine weeks.
*'''''Everything that is present in an adult human is now present in the small embryo''''' at eight weeks. <ref>[http://www.americanpregnancy.org/duringpregnancy/fetaldevelopment1.htm American Pregnancy Association]</ref>
