I am so sorry your friend is going through this, its my biggest fear is that i had one healthy child and then can't have anymore. I m/c at almost 8 weeks after seeing my baby twice and everything was fine there was no explanation as to why it happened either.

I do suggest that she seeks further help from her FS and that more testing be done, or if what another poster has said wasnt done then it should be.

I know the heartbreak of one loss i couldnt imagine going through 6. BIG to your friend.
