Ovulation

Had a almost positive OPK on the 5th but ran out of tests so I couldn't track after that to see the actual positive. Anyway, I figured I would ovulate around the 6th so me and Hubby BD. Well for the last 3 days I've checked my cervix & had EWCM, also noticed some pain in my left ovary area so I'm wondering is it possible that even tho I had a (almost) positive OPK the 5th that I could just now be ovulating? We've been BD just in case but it's confusing me. Lol
