I need help...my chart showed ovulation on cd 14...15 feb but after today'ss bbt it changed the date to cd 15...16 feb😲

If I'm not wrong the ovulation can be detected if the next 3 temps are higher then the last 6 temps...🤔

I got 4 temps higher in a row but it changed my ovulation date...☺

I got mild cramps last for few minutes on 15 feb and increase in cm on 14 feb's night.. Please let me know which one is accurate... Today's chart or the chart which I override...baby dust to all✨✨✨
