'Thank you so much! I will copy and paste your message!
Well then, fingers crossed I am pregnant then!! :-)
Just one last question though. I understand how a short LP could prevent pregnancy but what is the association with mc if your bodies hormones take over anyway?'

'They used to think that low prog could cause the lining to slough off and this would cause a loss of a normal pregnancy that otherwise would have made it. But subsequent study has seemed to indicate that healthy babies, once they stick enough to register on a preg test, increase prog all on their own by signalling your body to start cranking out the prog. And pregnancies that weren't going to work out, don't work out anyway despite the progesterone, and all prog support does is drag out a pregnancy that was doomed from the very beginning. If hte baby was developing right, it would have signalled the body to make extra progesterone. If that doesn't happen, it means that something was not right.
So basically, once you've have a pos preg test, all the prog can do is maintain a pregnancy that wasn't meant to work out - betas won't go up, the baby will stop growing, and eventually it will be a MMC (missed miscarriage) and the progesterone will need to be discontinued at that point to allow nature to take its course, or a D and C will be done.'
