I think I've got a surprise early O happening at the moment. Had two days of EWCM and my OPK was almost positive this morning so will check again this afternoon. So weird that it has decided to happen so early for me (I'm only CD10) but I was talking to my acupuncturist last night and he showed me a study printed in the British Medical Journal that looked at when women ovulated throughout their cycle. Only 10% actually ovulated between day 10 and 14 and also that women might have more than one fertile window each cycle. I found it so interesting and it proved to me the importance of testing and BDing right throughout a cycle! Anyway, a bit of food for thought!
