7.5 mg Letrozole and ovulated from 2 follicles!

Confirmed ovulation with ultrasound and now I’m 5 dpo. Is it normal to have positive OPKs after they have turned negative? I’m 5 dpo today and got these...

(Only took these bc I’m a POAS addict and I’m saving my tests 🤪 plus having some cramping on the side I ovulated from)
