Ovulation?

My FF chart is below. Got my first +opk on CD23, lines equally dark. Darkest opk on CD24, test line much darker than control. On CD25 it was back to equal darkness, then back to negative after that. Usually I ovulate about 72 hours after my first +opk, but I had tons of cramping and pinching on my right side on CD23, so is it possible I ovulated earlier than normal relative to my opk? I'm thinking no, since I had a darker positive the next day. Temp indicates I may have ovulated yesterday, maybe? I don't know. I know I should wait and see what temp does, but I'm impatient and DH really needs a break from all the BDing. I don't want to miss our chance, though.
