Here goes!! We have wanted to conceive for about 9 yrs now. I have one 10 yr old son...NO problem conceiving! I have just been able to go to an infertility dr. I have regular periods...almost pin point start date. In 1/12, my postgesterone level was 7....BFN. 2/12, round 1 of 50mg Clomid my progesterone level was 35...BFN. 3/12, round 2 of 50mg Clomid my progesterone level 32...BFN. 4/12, had HSG (no blockage) no Clomid...BFN. 5/12, round 1 of 2.5mg Letrozole my progesterone level 9...waiting on Day 1 of cycle to see if I'm prego. It seems like I'm OV, so whats some of reasons for BFN or what are some other thigns to try?
