Confused

I took a pregnancy test 9 days past ovulation. I started to spot 6 days past ovulation. Just light brown spotting for three days. I figured if it was implantation bleeding a test would be positive 3 days later. I started to spot again but only for two days. Not enough to use a pad and brown again. Fast forward I'm now two days late for my period. I never had a legit period and I'm normally early and pretty heavy. I'm now 14 days past ovulation. I don't have a pregnancy test and I don't want to buy one only to see another negative. A few days ago my opk was negative. I tested again today 14 days after my last positive and it's positive. Am I ovulating again? Is there a chance I'm pregnant? Maybe surge because my period should be any day????
