OPK confusion

So I got a smiley face on my CB digital ovulation test on the 7th (cd21). I am 12dpo and have taken a pregnancy test which was negative. I figured I'd try again the next few days. But randomly I decided to take an ovulation test with a different stick(apparently that matters) and it came back super positive. (My last one wasn't as dark so I was doubtful) now I'm guessing we BD like crazy. My questions are: could an ovulation test catch hcg hormones before my hpt? If I am ovulating now when should I take another pregnancy test? #longestcycleever
