I had my cd 12 u/s this morning to check progress this month and now I have too many immature follicles!! I did two unsuccessful rounds of clomid and this month did letrozole and follistim injections. I had two measuring at 12 and apparently a lot of smaller ones. I'm continuing my injections until my repeat scan on Thursday. She also checked my estrogen levels because of the amount of follicles. Said we may have to sit this round out to avoid ending up with quads, quints, etc. I'm so frustrated! I hate that there is nothing I can do but sit back and wait...
