OVIA or GLOW?

Who has actually fallen pregnant from the help of this app, with your fertile days and what not? I'm not spreading any hate, I have two apps, OVIA and obviously glow, OVIA is saying I don't start my fertile window for another day yet glow is saying I'm 2 days in.. I'm just wondering people's thoughts and their experiences..
