Ovulation test after sex??

Mo

I got my peak on CB advanced yesterday morning (cd 12). Took a first response ovulation test just to confirm. Checked again that night. Those are the most positive first response I’ve ever gotten so wasn’t going to test anymore. But this morning I had sex and when I went to pee after, I had a test sitting there so I thought why not. The test line was actually darker and I’ve never had one that dark (ttc for 6 months). So would peeing after sex make a test more positive or is it just a good test? I haven’t been testing after I get my peak on CB so just curious.
