There are medically necessary reasons to have to abort even a near full-term pregnancy. My mother had a stillborn at a little past six months, which doctors knew was dead weeks before she delivered. Abortion was illegal. She was sent home to wait for her body to "take care of it." Weeks later, she spent nearly two days in labor. The fetus facial features had not fully formed.
Another example, I had a college friend who married when she graduated. Very soon, she was pregnant. They very much wanted a child. Sadly, the baby died in utero a couple of weeks before her due date. A Southern Baptist herself, she was being treated in a baptist hospital. The hospital refused to perform an abortion. They wouldn't even perform a c-section. They induced. She went through more than 30 hours of hard labor to deliver a corpse. Yes, she could have gone to a different hospital.
The point is, there are valid reasons for late-term abortions. Those reasons are, without exception, because something has gone catastrophically wrong in a pregnancy. It's meaningless to limit abortion rights to a number of weeks at which possible viability occurs. Abortion is healthcare and may be necessary at any stage of a pregnancy. Only a patient and their healthcare professionals should determine that.
