I'm on CD28 to today and got a very strong positive opk yesterday....CD27. My cycles are abit all over the place atm but last 2 have been 32 days. Is this abit late to be ov'in?! I'm confused. I've been having cramping for the past few days, did another opk this morning and second line has faded a little from yesterday?? Anyone else had a positive opk late in their cycle?
