I have PCOS and haven't had a "regular" cycle since I went off BC in March. In November, I was on progesterone to induce a period (came on 11/21) and then took Letrozol for five days to help ovulate (LH surge detected on 12/7). Any suggestions on when I should be taking a pregnancy test or expecting my period to show up? My doctor had me take progesterone last cycle on day 35 if there was no period and a negative pregnancy test.
