Fertile window.

Hello. I need some people’s input about when are the most fertile days. So I have two apps to track my period with. This one and the app known as Flo. I’ve had Flo longer than this one by a few years and this past year, Flo has been saying that my fertility window is only 3 or 4 days after the last day of my period.

This app shows that it’s a week or so later than my last day of my period. Has anyone else had their fertile window so soon after a period? That’s what I’ve been going by for the longest and it just doesn’t seem correct. I would appreciate anyone’s feedback on this. Thank you!
