Sometimes even with that number of follies your hormone levels can be just low enough. I have always had over 50 follies (except last cycle where I had around 40), and other than the first cycle which was cancelled, I had pick up each time. My levels were high, but they determined not so high that I couldnt go ahead with OPU.

Crossing my fingers you get that chance...

Im sure you will already know this, but drinking as much water as possible helps with reducing hormone levels.
