I am undergoing <a href="https://glowing.com/glow-fertility-program">IVF</a> was on birth control until 4th April. I have been spotting but no periods yet. I am supposed to have a baseline ultrasound on the 11th. Currently on lupron and doctor told me I should get my periods before the ultrasound. Can I be on my periods during ultrasound? When should I expect my periods to actually come? Just cramping and spotting for last 3 days!! Driving me nuts!
