We have been TTC for 7 months. I have always had irregular periods, going 4-6 months betwen them. The doc put me on provera to make me start my period, and then clomid 50mg. No ovulation. Then tried 100mg and my progesterone levels were the same as on 50mg, low. So now he is prescribing Letrazole. Has anyone used this for ovulation? Would like to hear about some experiences please!! Would love a positive outcome
