Ovulation jumping around on calendar

Hey, has anyone had this happen where glow shows you when your estimated ovulation is (when we all know it's not 100%) but noticed yesterday it changed. I wonder why? I logged ovulation testing last few days so would that be the reason 🤔 or is the app just being silly. I know I had my ovulation before the dates shown on the first pic because sometimes now I get mild cramps or discomfort from ovulation.

Wanted to add that I believe I actually ovulated on 6_7th of March because of the cramps and I regret now from now testing then to confirm for ovulation 😅
