OPK Confusion

I’ve been trying to figure out when I’m ovulating and not having a ton of luck. My period is late (cycle is crazy), negative pregnancy test, but looks to be a positive ovulation test (pic below)? I’m super confused bc when I snapped a pic on the <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> it’s reading the OPK as very negative. The test line is 100% darker. Has anyone experienced this? I’m going to my doctor on Monday, but I’m just trying to understand what’s going on...
