So I have 2 different period trackers and they say 2 different things! Has anyone else experienced this before?? Like one says my period will start today and the other says it won't start until next Saturday 🤔

I'm having the same issue with my days and Ovia about my fertile days
@b3autifulm3ss, I wonder why mine is such a big difference and which one I should follow 🤔
@lezbemoms16, mine said 2 days difference but not that big of a difference
