3 days late, negative HPT, positive OPK

Ezzan

Hi, Im 3 days late for AF. So likely im around 17-18 DPO.

So I did HPT before AF due but I got BFN.

Since I have EWCM dischage around 4-5 days, So today I took OPK, and the result almost positive, if you can see in the picture.

Im so confuse right now, AF didnt show up, and all HPT are negative. Am I ovulating or what?
