Running 3 apps, all different

Keighley

I am running 3 apps, all giving me different results

Ovia

FMC

Glow

As 2 apps come back saying I was due on today I took a pregnancy test which was negative.

I haven’t started tracking my temp yet. I am waiting for this cycle to start.

I had egg white discharge on 19th.

Does anyone else run multiple apps that also give them different results??
