Hi. Can anyone help? I have been TTC for over a year and recently went to see my doctor. My periods are irregular (cycles between 28-40 days) so I had a 21 day progesterone test. It showed, apparently, that I'm not ovulating. However, I am now on day 32 and still no period. Nothing unusual in that but I've read that that means the test is invalid. Is it possible that I'm actually pregnant. Or would the 21 day test have shown that?
