I know if your progesterone is low they will put you on a supplement to prevent m/c, especially if you have m/c'd in the past. I don't know though what is considered low though. When I m/c'd they didn't see anything so I really don't know about the fetal pole and all that. Good luck with everything and don't hesitate to go the ER if you are in any pain or bleeding more than usual.
