So because some miscarriages are induced by a pill, and it’s essentially impossible for docs to distinguish a natural miscarriage from an induced one, the state has an assumption of wrong-doing. From the article:

This means that pregnant people who are actively miscarrying may be denied care if there is still detectable fetal cardiac activity. There have already been reports of such situations in Texas and Louisiana. In Louisiana, for example, a pregnant woman went to the hospital after experiencing sharp pain and bleeding. She was informed her fetus had likely stopped growing a few weeks prior, as its size did not correspond to the length of her pregnancy, and that it had very faint cardiac activity. Despite the pain and the blood loss she was experiencing, she could not receive the regimen of mifepristone and misoprostol commonly prescribed to pregnant patients who are miscarrying to ensure that the pregnancy is safely expelled from the body completely in a timely manner, thereby decreasing the risk of sepsis and infection. Instead, she had to wait for the miscarriage to progress without medical intervention, which would have expedited the process and reduced her medical risk. In states where the abortion bans do not clarify that miscarriage care is not criminalized – even when there is still detectable cardiac activity – pregnant people may not be able to receive care to manage their pregnancy loss unless and until it becomes a medical emergency.

I’ve also heard that women in some US states are denied treatments that can cause birth defects even if they are not pregnant.

This is all so extremely fucked up it’s hard to believe it’s true.
