4 DPO and OPKs are still positive??

Ovulation was confirmed 02/22 (on clomid w/ supervision). I had blaring positive the day before, the day of, and the next day, aaaand the next day. 3 DPO, the test was still dark, but not quite positive (just about as dark as control line). Now, at 4 DPO, positive again! Lines are the same darkness. Has anyone else had this? On online forums, it's usually updated with a BFP, but I don't see how that could be a catch-all considering there's no way it's even implanted yet.

Here's my test, with a dye run in the corner (which is why there's a bit more dye on the bottom of the control) :

I took it after an easy@home, which I don't like as much, which was also positive. That one is in the trash now lol.

And for anyone who wants to know, I'm peeing on sticks at 4 DPO, because I'm addicted to it! Lol, that's what ICs are for, right? 😂
