Period in your FET cycle?

Jessica

I just got my approval for our first FET! Yayyy!!

One thing I can't figure out (and don't see the Dr till Monday) is my period. I'm on BC pills, cycle day 20. My first estrogen pill is supposed to be on cycle day 26. Will I get a period? Or do the meds keep my period from happening? I tried googling and can't get the right search combination.
