Yes I started cetrotide on day 5 of stims.
I'm not sure what the reasoning for this was though I did previously ovulate early on the microdose lupron protocol.
I had a day 7 scan, day 6 of stims, and only had 3 follies of about 6mm, however things took off and I'm now ready for EC with 5 follies though I was stimming for 14 days.
I would say the cetrotide possibly slowed things down and possibly gave more even follicle growth but who knows?
I'm just hoping I don't surge through the cetrotide but my b/w looked OK yesterday so fingers crossed!
