I have taken the suppository progesterone. It is a compounded form of progesterone that is made specifically by the pharmacist. My naturopath highly recommended it for the reasons you mentioned. It is a "natural" form of progesterone so I think it may be slightly different than the prometrium but honestly I am not 100% sure.
I took it with my ds pregnancy and still bled more than I would have liked through the first trimester. But he is here an healthy now! Oh, and I took it up to about 16 weeks pregnant.
I also was taking it with my last pregnancy and although it keep the bleeding at bay, the baby stopped developing early and I had to stop the progesteone to let nature take it's course.
If you are taking it, get hcg levels checked regularly. That way if the embryo stops growing you will know you need to stop taking the progesterone. Otherwise you can make things linger on longer than they naturally should. I know that it may be a hard thing to think about, but...
