Any success on multiple rounds of femara??

Emilie

I was on 4 cycles of clomid 50mg -150mg and my progesterone stayed at 7. I asked my doctor to change to femara 2.5mg and my progesterone doubled and was 13. But I got a BFN. Has anyone had success and gotten a BFP on multiple rounds on femara? Would going to a 5mg dose be a bad thing?? I am picking up my femara today so I can start my second round tomorrow morning! Praying I am able to get my bfp this month!!!
