I use glow every single day which is suprising because I usually forget about apps after a week lol. But this one is amazing. I don't know if it's allowed but I also downloaded this other app that actually tells me how many days till I can take a pregnancy test. So no guessing lol. It's called ovia fertility. I will always use glow as my fist go to app. But figured you ladies might also like this. No rooms to ask questions though, which sucks. But it is very helpful.
