I did a lot of cycles and did both and didn't notice much of a difference. I probably felt cd2 was a smidge better, but not sure there is any evidence either way. Go with what is convenient for you.

Clinic is giving me the option of choosing CD 2 or 3 to do baseline and start injections. Are there reasons to choose one over the other? Will follicles develop slower if I wait until CD3? Or does subjecting them to one day fewer injections have some benefit?
