Waiting on AF after a loss

Mi

So I had my miscarriage in December and hysteroscopy in Jan. Still no period. I’m starting to panic bc my doctor said I had to wait two cycles to transfer my last embryo and I have not had one yet. I was hoping for March, but that is not looking likely. Infertility sucks. The time that I need AF to be on time that B%$¥#@ is no where to be found. 😔. How long did it take for your period to come if you have suffered from a miscarriage?

Already tested to make sure, BFN.
