OPK Help!

I've been using these ovulation strips starting a few days after my period ended. As you can see, the test line has always been faint, and the control line has been bold. Since CD12, I've been testing twice a day (morning/evening around the same time). I just tested for the second time today (CD15) at 7pm, and it looks to me that the test line is showing more visible than it has been, but not as bold as the control line. According to Glo and other tracking apps, I'm supposed to ovulate CD17. Should I wait to see what the next two testing days show? Or, should I assume that this test is telling me I'll be ovulating in the next 12-24 hrs. Somebody PLEASE HELP ME 🙏
