A question for those of you out there supplementing with progresterone: I've had a few (4) miscarriages, and the recurrent miscarriage clinic told me I should start taking progesterone 72 hours after ovulation. I don't have a luteal phase defect, and my progesterone measures normal (but that was only one blood test, and I've read that you need a few tests to get an accurate picture).
Anyway, I am a bit leery about taking something for which there is no demonstrated need. Of course, that wouldn't be quite enough to stop me from taking it, given that you never know what might help with unexplained recurrent pregnancy loss. However, I am also worried about the safety of progesterone supplementation during pregnancy. Whenever I ask any of our docs about it, the response is always "well, your body naturally produces progesterone, so I wouldn't worry about it". Sure, but our bodies naturally produce estrogen too, and look what happened with DES.
Has anyone found any convincing information suggesting that progesterone is safe during pregnancy? Am I missing something here?
