I have a friend who is currently approx. 5w1d pregnant and has been spotting for the last week on and off. She had a beta on Monday (139) and on Wednesday (179), so it definitely is not going up like it should. She found out today that her progesterone is only 1.9. The OB said that it is too late to add progesterone supplements and they are having her go in for another beta tomorrow. She has already had 2 MCs and 2 CPs. Is it too late to supplement progesterone for this pregnancy? In the future, would she supplement progesterone every month of TTC or only when she gets a BFP? Her OB isn't being very helpful.
