Confused with OPK

I'm so confused with the OPKs.

Yesterday I had a positive OPK in the morning but negative the rest of day and today. We BD 25 & 27 and yesterday we my positive OPK. Today it's negative and the app shifted to say I ovulated. So do I keep BDing the next few days? Or is it a lost cause now?? So confused
