Follicle question

Melissa

Hi ladies! So I just had an ultrasound today, I'm on day 7 of stimming and they only saw 3 follicles. I'm super bummed and worried I'll have a canceled cycle. My RE has me adding in Clomid now and I go back Wednesday for another US. My question is-can more follicles pop up? And would it be worth it to go through with ET if I only end up with the 3?
