I'm trying to work out whether I've ovulated, and thought the MN ladies would be able to help me. Basically, I thought I'd O'd last night (positive OPK test in the morning and at lunchtime, loads of EWCM and ovulation pain yesterday evening). No temp rise this morning, but I thought maybe it just hadn't kicked in yet. But when I did an OPK test at lunchtime today, it's still positive. Does this mean I haven't O'd yet? Or is it possible to have a residual positive OPK test even after ovulation?
