Tamie,
Hugs to you. Although, I haven't been exactly where you are I do know how devastating and frustrating this whole experience can be. First of all, take care of yourself. Even if it meand curling up and shutting yourself off for a few days. You need to heal emotionally. Then I would definatley consider seeking the advice of a fertility spercialist. Maybe he/she could provide you with the necessary answers. As others have stated I have known a few peoplewho needed progesterone (I did) to sustain a pregnancy. I also had a friend who suffered multiple miscarriages and needed baby aspirin a s a blood thinner. A specialist can really help you fiqure out what needs to be done in order to sustain the pregnancy (obviously you were able to get pregnant). Good luck and prayers for your journey.
