I Had Abdominal Pain For About 24 Hours Straight, Right

I had abdominal pain for about 24 hours straight, right while I was having egg white cervical mucus around the time of month I should ovulate. All of a sudden, I had a mini gush of watery discharge that felt like I leaked urine or something. (It wasn't.) But my stomach almost instantly stopped hurting for good at that moment I gushed fluid and from then on my stomach was fine. Was this possibly the very moment that I ovulated? I'm asking because we had unprotected sex 12 hours after this incident without thinking and took plan b about 18 hours after that sex. Can plan b still work if I ovulated before I had sex? And does the body sometimes gush fluid when the egg is released during the fertile window?
