last month was my first month
and femara. I had the same spotting, and my cycle was also 30 days. (usually mine is 35 though, so 30 was better for me). . . the spotting bothered me too, I kept hoping that it was implantation bleeding. But no, finally af came full force. This is my second month on it. I o'd the same day this day as last month, so expect the cycle will be 30 days again. Good luck with your IUI!!
