I usually ovulate between cd14-16 but this month I detected a surge cd9 and dried up immediately (I usually surge and o on the same day). I'm annoyed as I hadn't started BDing. I started getting the flu cd11 and is now cd12. Could I have another surge because of illness or is that it for the month. I have a leutal phase of 16 days so does that mean a 25 day cycle (as opposed to normal 30-32). Sorry so many questions!
