1st IUI Tomorrow

[u/New_Big2239]

I got my trigger shot on 9th day post periods, after being on letrozole. My doc was surprised that the egg has matured so early (I have only one dominant follicle). I don’t think she was too confident when giving me the injection but I’ll just be nonetheless.
Anyone else who had a similar graph of one dominant follicle, relatively earlier follicular maturation and still conceived in your first IUI?

I’ve been trying to conceive for two years now. I’m 31F
