OPK help

I still haven’t had a period, I’m almost 12 months pp and been testing on and off for a month now, on Wednesday I got these OPKresults, (top one looked positive but then two hours later I tested again because I needed confirmation and it was negative? So i did another a few hours later and even more negative?) did I miss ovulation? I didn’t test the night before as it was negative that morning. I’ve calculated when my period would be so I guess I’ll just be on the look out. But we would like to get pregnant soon if I can catch ovulation!
