Help too many Fertility apps!

Stacey
So I joined this app 2 days ago as I've already been trying for baby #2 I have been using two prev apps My days & Ovia, Ovia has told me to test everyday and that my period was due a few days ago but 6 negative tests. My days app is saying test in 4 days whilst GLOW is saying test in 2. I've spent a fortune on test, I am so desperate for baby #2 and don't know with all these apps it's so confusing! PLEASE HELP
