I just had a follicle study yesterday at CD 17 to see if I had ovulated. It looked like I had via my chart, but when he did the vaginal u/s it showed two very small cysts on my left ovary and nothing on my right; he said I did not ovulate and it might have been due to me starting to bleed on my own and it was going to be an anovulatory cycle. I have PCOS and I bleed all the time (I bled 15 days just this last time). He is giving me 5 mg of Letrozole (Femara) again. My question is has anyone not ovulated on 5 mg, but then the next month ovulated on the same dosage they had not ovulated on previously? I did not respond to Clomid and I really want this to work; also the 2 small cysts could they have been gearing up to ovulate but just didn't release? He acted optimistic and I just don't want to read too much into anything.
