Hi TerryLynnh,
I am going to post my own similar problem, but I wanted to say that I also can't tolerate progesterone. I have tried different kinds, (bio-identical),and they all cause me IBS cramps bad enough that I can't use it. I have estrogen dominance, and had surgery last year to remove an endometrioma, aggravated by excess estrogen. I am working with my doctor to try to balance my estrogen metabolism, and all I can say to you now is, I am still trying the progesterone occassionally, finding that sometimes I can tolerate it and sometimes I can't, but I also take a product called EstroDIM. If youh haven't heard of it, it is supposed to help metabolize estrogen. I don't know if it is helping me yet, I just got retested and don't have the results yet. BUT, supposedly this suppliment works very well for some people. It might be a start for you, is harmless (made from cruciferous vegetables), and you might want to do some research or ask your doctor about it.
I hope this helps or gives you some encouragement. And, you are not alone on not tolerating progesterone. It is soooooo incredibly frustrating and scary. But you are not alone. Don't give up hope though, keep working with your doctor, or try a different doctor if need be.
Val
