Cycle days

I’ve been keeping track of my period and such for years.

I was put on birth control at a young age for my “moodiness” and thus I went from 7 day periods to 3 day periods and it’s been that way ever since. Even after I quit taking birth control.

I average 21 days between cycles. I’m averaging 1-1 1/2 weeks between what the app has as my fertile week and my period. I can’t change it past 22 in the settings.

We’re currently trying to get pregnant for 5 months. Nothing yet, but I’ve looked into Conceive Plus and getting ovulation tests to help pinpoint where it happens.

Does anyone have experience with this?
