Hi we had this on my first she's now 14 months. They gave us an extra growth scan at 30 weeks roughly and everything was normal. After having her they took it away to be tested I'm not even sure for what tbh but it all came back clear and we had a healthy baby girl.
I have not had this happen. I did a quick Google search. I found that the risk of still birth is minimal. The heartt and kidneys develop at the same time as the cord. Doctors usually check these organs closely to make sure they are developing properly. I also found the baby is usually born healthy without complications.
I can't answer that question cause I've never experienced it but I did want to let you know that someone is here... I don't want you guys to worry...
