When did I ovulate?

[u/redheadedblondie13]

I’m so confused! Is it 24 hours roughly after the first positive? Day 20 is positive, or is it 24 hours after the peak. Also due to conflicting work schedules we only had sex on cycle days 18&19.

It’s 24 - 36 hours from when you see the first positive! It’s always been 24 hours or less for me. CD 18 and 19 is still great coverage!
