I've heard of this before Elyse I don't know tons about it but I know there is a suspected link.

Coeliac disease runs in my family, I don't have it but a couple of my aunt's do. One of them had a few miscarriages but she also had two full term pregnancies that were normal and uneventful. The second one though, the placenta was very small and she was told that it was probably related to coeliac.

I'd encourage you to do some research because not alot of obstetricians would be really up on the link so if you educate yourself that's the most proactive thing you can do.

Good luck ttc.
