Question for you ladies who chart and take OPK

Hi Ladies

Currently not charting but I will start next cycle.

For you ladies who use OPK and chart I am wondering is 1 day after positive OPK accurate for you in terms of temps indicating when you ovulated? Or is it more likely 2 days? My friend doing both and thinks she ovulates 2 days after positive OPK- I always thought it was 1.

Thanks 🙏
