Does Estrace shorten your period?

Ke

My baseline for my FET was on Tuesday of this week (Day 2 of my cycle) and I bled heavy (heavier than I ever have with lots of clots) Tuesday and Wednesday, then Thursday just a little tiny bit and today it’s gone. This is not my normal period which I know after retrieval it can be different. But I’m wondering if starting the Estrace on Tuesday shortened my period or something? Anyone else experience this?

I go back in for another ultrasound/monitoring on the 22nd to determine when to start the PIO injections for transfer.

Thanks!!
