On Tuesday, Ohio Governor John Kasich signed into law one of two bills that limit women's reproductive rights in the state.
Kasich vetoed the so-called "heartbeat bill," which would have banned doctors from performing legal abortions on women with "a detectable fetal heartbeat."
But Kasich signed another anti-abortion bill sent to his desk, and it bans the practice after 20 weeks of pregnancy. If a mother's health is in danger, the law makes an exception - though it does not make exceptions for when pregnancy results from rape or incest.
Below are the key biological stages of pregnancy as they relate to a developing baby, including when its heartbeat is first detectable and the 20-week mark.
