OPK positives/ovulation

Yesterday morning I took a clear blue test with the smileys and it showed up with a smiley face at around 9am. We were out shopping around 6pm and I started to feel ovulation pain, we BD around 830pm when we got home, I took another opk test later that night around midnight and it still showed a smiley. This morning I took a test for the heck of it and no smiley showed up, should we still BD tonight or since I already had ovulation pain yesterday, did I already ovulate??
