Need help with positive OPKs

Nakita

Okay, I need help. I thought I'd try an ovulation test yesterday for kicks and giggles so now I'm really confused. I don't even know which day I originally ovulated anyways ( got a peak on CD 15 & CD 16) so any help is appreciated. Included a pic of the positive Opks on CD 15&16, the one from yesterday, and a hpt I took yesterday as well..
