Help confused

Carissa • Mommy to a 3yr old girl and pregnant with baby #2🤰🏻

Okay so I got my PEAK ovulation the one where the test line is darker then the control line on 1/12

Is that the day you ovulate? Or do you ovulate 12-48 hrs after that?

If that was ovulation day then it 11 dpo.

If it could be up till 2 days later can I only be 9dpo?

I’m so confused.
