I was on Femara last cycle and I did not ovulate. My body tried but follicles stagnated at 13mm for a few days, then receded. This was totally odd since I have not known myself to not ovulate and was taking it primarily for Luteal Phase Defect. I am now in a quandry about how to move ahead this cycle, given I don't know how to deal with an anovulatory cycle. Reason they did Femara is that Clomid thinned my lining.
I have no success to report, though. I may move on to injectibles after another round of Clomid (they will supplement with estrogen to try and rescue my lining, which worked last time it thinned).
Best to you,
