HR 490 “the Heartbeat Protection Act of 2017” is effectively a total ban on abortion — nationwide. This bill would prevent a doctor from performing an abortion if a fetal heartbeat is detected. For many women, this means that by the time they know they are pregnant, an abortion with not be legal. Desperate and without a safe procedure available to them, many women will take extreme measures to abort their pregnancies.  This means a return to "back alley" coat hanger abortions.
