Vvvvfl? Positive OPK negative HPT 12dpo. Confused.

Br

So I am on CD 26, 12 dpo according to a positive OPK, EWCM, and right side cramping on CD 14. But last night I started having very strong back cramps on my left side, just like ovulation cramps. Took an OPK this morning and positive (first pic). Took HPT and it looks pretty negative to me, but thought I’d get another opinion. Do implantation cramps feel like ovulation pain, or is it more likely that I am ovulating late and that my first positive OPK earlier in the month was a fluke? 🤔
