Hi there, I am doing frozen embryo transfer, I was put on birth control for the last 5 weeks, then I was instructed to take my last pill on Jan 15; they told me I should get a period within a couple of days after, then start my meds (estrogen pills and patches) on jan 19 after doing blood work and ultrasound. However I didn’t get a period, I’m just spotting, so the clinic said that I shouldn’t start my meds until I get a full flow period. I am really worried now as I am not getting my period at all. From my understanding the whole idea behind taking the birth control is to stop ovulation, but what if my body starts ovulating to get a period. I don’t have many embryos and worried something would go wrong. Anyone has gone through similar situation before?
