Opk test wrong?

I had some spotting and cramping a few days ago, the cramping got really strong in the evening 2 nights ago. I had thought I already ovulated last week so I was hoping that was implantation, well I decided to take an opk the day after my strong cramps and spotting and it has been reading positive the last 2 days but my symptoms are gone, no cramping like I had before or spotting... so my question is, was the spotting and cramping from my body releasing the egg 2 days ago? but my LH surge is just a long one and reading that I am still ovulating? I don’t know when my LH surge started because I had no tests and had to go to town to get them so I’m not sure how long it could have been reading positive before? These are my last two tests
