Ovulation tracking help!!

Veronica • 26✨PCOS warrior✨💪🏻 mama to be 5/18/2024💙☺️

So I’m currently on day 8 of my period (lately my periods have been every other month and have been lasting a month) i started taking metformin in December of 2020 so I’m hoping that’ll help regulate my periods. This period seems to be lighter than the last 2 so I’m hoping it’ll end soon. However, i wanna start tracking my ovulation and I no idea when to! I’ve heard to start tracking 4-6 days after your period, but when i look at my period tracking apps all of them are saying different dates!😩 one predicts I’ll ovulate the 7th of March, the other says the 17th of March and the last one says the 12th/13th of March. These apps obviously don’t know I have PCOS. So the predictions are just that😂 does anyone have any advice for me? I’m currently taking clomid.
