I suffer with pcos and am suppose to be going for clomid next thurs but yesterday I had a scan to check my ovaries and the lady who did it said that my left ovary was clear and enlarged and had recently ovulated, she also said my lining was nice and thick, she said the doc will want to do a blood test next thurs with these kind of results and she said it was to early now to confirm but she said I could be pregnant, I had had sex recently on days 15-17 and today is day 21 of cycle but these are irregular. Could I be? I have had cramping the last 3 days on and off and have felt very tired but too hot to sleep.
