One 21 mm follicle finally grew so I triggered this morning and will have IUI#2 tomorrow morning. Please send fertilization vibes my way circa 9 am EST. ;D
I don't know much about IUI, but because you only had one follicle, does this mean that the risk of twins is not there?
Yes! If there's only one follicle the odds are I'll only release one egg. Although there's a (rare) chance that one follicle could have two eggs or no eggs at all.
