I think they can give you a trigger shot to make you ovulate the cyst, or they can drain it. I have heard that the draining hurts but is bearable. I think trying to ovulate it would probably mean you have to wait til next month to transfer.

I was on BCP for about three weeks, and a cyst that was discovered during that time has still not gone away and continues to produce estrogen. I'm on Lupron preparing for FET, but they have delayed starting the Estrace and taken me off the pill since it wasn't doing anything to help the situation. I have had cysts before a stim cycle, but they have never been producing estrogen and we just moved right ahead. What are my options here during this FET prep period? I'll find out more tomorrow, but I just want to prepare myself and better understand what questions to ask.
