My wife literally had to have all three of those while we were trying to have our twins. She had a double whammy of a rogue ectopic they couldn’t find on scans and an empty gestational sac in the uterus that wouldn’t pass. They knew there had to be an ectopic somewhere because her hCG levels weren’t tracking with what they should be with what they could see on the scans.

So the Catholic hospital we were at gave her multiple courses of methotrexate to make sure they got the ectopic. Multiple scripts for I believe it was Misoprostol to try to pass the miscarriage. But when that didn’t work and she showed up to a monitoring appointment with signs of sepsis, they immediately took her in for emergency surgery to remove it.

Then when we finally got our twins we had to do a late term selective termination because the pregnancy was originally quads, one died early enough to be reabsorbed but was conjoined at the umbilical cord to her twin. That twin had a massive stroke during some crucial brain development weeks and we found out at 20 weeks that she had basically no brain and her constant seizures were actively killing the other two and might even cause her to lose the entire pregnancy.

Literally the only option to save the two healthy twins was to terminate that triplet. Abortion is literally the only reason my twins are alive today.
