I didn't do FET w/DE but I was on BCPs for about six weeks with my FET. That was partially, though, because of my PCOS. The RE said the male hormones needed to be extra super suppressed. (I think that's the technical term, "extra super suppressed." You can tell that I'm an expert at this stuff, right?)
I was then started on PIO and estrogen. Started PIO once a day, then they bumped it up to twice. Sorry I don't have a better calendar for you. I'm pretty lazy about my past cycles. It's like I have a mind-wipe after each BFN.
Good luck to you and thumbs up to celebrating with some champagne when your donor signs her paperwork. FX!
