af due feb 3rd or 5th

Glow says the 5th, another app I have called flo says the 3rd. (Glow and flo, lol). My fertile window is coming up soon, both apps mostly have the same fertile days. 3rd month trying! I'm hoping this is my month. I don't track ovulation with opk's or temping or anything, I just kind of have sex all the time and hope for the best lol. Anyone else due around the beginning of feb?!
