u/shelbykrose

I'm trying to do my first IUI this month. I have unexplained infertility (no PCOS) and was given 3.75mg letrozole on cd 3-7. I was scanned on CD11 with one 14mm follicle and went back today (CD13) and it has not grown at all. I'm feeling so discouraged. Has anyone had experience with this? My doctor told me to take 5mg of letrozole today and tomorrow and I'll rescan on CD15. I don't know why that follicle stopped growing and I don't know what's wrong with me!
