Progesterone and AF

[jodylovesscotty]

I did a search, but couldn't really find what I was looking for. I am on progesterone suppositories. I am pretty sure I am not pregnant(got BFN at 13dpIUI), but waiting until Sat. for my RE to test me. If I stop taking it on Saturday, when should I expect AF to come (I am pretty regular to begin with)?

When I was taking prog supps AF arrives right on schedule even with me still taking the supps. From what I have read/heard every woman experiences this differently some won't get AF if on the supps. others do. But generally it is out of your system quite fast so AF shouldn't take long to show.

Sorry to hear about the BFN. :( For me, AF always came 2-3 days after I stopped the progesterone supps (I was on 100mg twice a day).
