I agree with the PP, see if your doc will supplement. I used the vaginal suppositories with my first pregnancy and will again if needed. I go to the doctor on Monday. From what I have read the suppositories are basically the same as what your body should be producing anyway, so they are safe. You may read lots of stuff about dangers of progesterone supplements in pregnancy, but my understanding is that refers to synthetic forms. You will have to get the real thing from a special pharmacy and it will have to be refrigerated and made on the spot.
