I had a 40mm cyst last month and went on BCP's for 3 weeks. It was down to 10mm and we started a letrozole cycle 4 days later with a menopur booster on cd9. And today it looks like NOTHING is happening. There is one 7mm follie on the left but that could be the residual cyst. No other follies anywhere(not even little ones) which has never happened before. Just wondering if this happened to anyone else. I am wondering if we should just wait and go through one natural cycle and let my body get back into its rythym naturally...maybe all these meds are messing me up???
