HELP!!

Alicia

Ok I have 2 cycle apps.. one I've been using for 3 years and this one... they have both always been in sync.. until this cycle... one app says I'm 9 days late.. while glow says 2...

I'm saying all of that to say this.. my period is like clock work NEVER late.. I've had creamy white discharge and cramps for three days now... when should I take a test???
