ovulation help

(keep in mind i’m on bc)

i’ve had this cm for a couple days now. ovulation test came back positive.

does anybody know what’s going on?

had sex the 15&16th. also what are my pregnancy chances knowing when i has unprotected sex, my cm and that the ovulation kit was positive?

very thick and not stretchy. when i try to stretch it- it makes little peaks like those and breaks ^^
