As I was reading your enteries I thought I wonder if she has Polycystic Ovary Syndrome. I had alot of the same problems your wife is having. I also took the provera to get my cycles. I took another fertility drug..femara for 4 mos and had weak ovulations. We just recently went to an RE and he diagnosed me w/ PCOS..this causes you to not ovulate...and as I understand there is help for this. You mentioned that her dr wants her to get her blood taken immediately after she takes the clomid...it typically is taken 7 days after ovulation to check progesterone wich lets you know if you ovulated.
Her body could ovulate on its own when she gets "regular" but there is always the question how long are you willing to wait? So many women have had such good luck with the fertility drugs...that I think it would be worth a try. But I would really have them check for PCOS.
I also know what you mean about "are we messing with God's plan?" I worry about that too...but I guess I try to think that if it's not in his plan it won't happen no matter what we do. Maybe his plan is for me to go through this and come out sronger to help someone else?!? Well good luck and tell your wife to hang in there..this is defenitly a rollercoster of emotions.
