I am preparing for FET. I took my last BCP 3 days ago and started oral estrace 2 days ago. This morning I woke up bleeding. I thought I would not get a period while on any of the meds. My FET is Scheduled for April 17, 2018. Should I be worried? My clinic is closed on the weekend but there’s a number to call for emergencies, however, I not sure if this is an emergency or just something normal?
