I am going in for my 3rd IUI tomorrow morning. I have been taking Letrozole and had the HCG trigger this morning. I had 2 good follicles on my right side (19 and 21.5) and a not so great one on my left side (13-14). In the previous 2 IUI's I have had 3 follicles-but the lead weren't so big as the one's this month. I did get pregnant with my 1st IUI, but it ended up being a chemical pregnancy. I want so badly for this to work this month. Does anyone have any success stories for only 2 follicles. I know it only takes one, and I pray that it works. Thanks for all your help and I pray for all of us every night.
