Flo VS Glow

🌛

Hello Ladies, I'm new to this app. I'm currently confused on when I ovulate(d). I've been using the app Flo for 17 months and it's always been correct on when I'll start my period, give or take a day. however I've been TTC for 5 months and I figured I'd try another app which brought me here. With that being said, why am I having two different days for ovulation? I have put all my info in from Flo to here. What one do I follow?

Flow says the 28th of May.

Glow says the 1st of June.

have I ovulated or not yet?
