I am a bit confused Squid. Did you say because you have a vaginal prolapse and low papp-A you have been put on bed rest?

Statistically low Papp-A puts you at higher risk of a growth delayed baby. The placenta doesn't last as long and early delivery can be rerquired. You will see though colloquially that isn't always the case (nor is it statistically!).

Really it's a matter of waiting and seeing. It will be great to get a good cardiac u/s done so they can rule out that issue.'

Have you been referrred to a specialist about your vaginal prolapse? There are things that can be done to help you through the pregnancy. If you haven't been referred ask to be.

Congratulations on another little boy...
