Hey all. I just finished my 4th cycle of clomid 100mg and AF came yesterday. The clomid is working (great follicle size) but we still haven't conceived. My doctor told me I needed to come in while I was on my period this time, but he didn't tell me why. Has anyone had their doctor tell them to do this? Does anyone know why? I know they want to do the hcg shot this time but I didn't think I did that until like day 14.
