Confused? Positive or Negative?

K

So I'm 12dpo and 3 days until AF is due. I have tried so hard not to test, so I did an experiment- I used up the rest of my dig. advanced OPKs. The were really faint to start, and then progressively got darker. This morning I got the solid smiley and the test line was very dark.

Against my better judgment, I got some HPTs. Um, I'm a little confused with the outcome:

The purple is the OPK. So my hormones are high enough for a positive OPK. Any thoughts? 😐 🤷🏻‍♀️
