On CD15 with absolutely no sign of a positive OPK at all Usually start getting faint ones around CD9 and dark CD12-14 then light again. My temp took a dive yesterday then up again today. Have I got a dodgy batch of OPK's? Am I still waiting for OV? Last month I had every pregnancy sign in the book including increasing temps until the day before AF arrived, one day early. I do wonder if 'something' may have started to happened which would explain my very heavy AF. Any ideas ladies.......quite despondent, which is not like me at all!
