My mom's stillbirth at 21 weeks was because of this, and probably her 3 miscarriages too. Sorry I don't have anything positive to share. With Bethany, the placenta started to pull away as the uterus was stretching funny and was bleeding and it got infected and almost killed my mom.
They didn't have ultrasounds or anything back then though, so they didn't know there was a problem or they probably could have helped it. So hopefully since they know this early her story has a better ending.
