Question! Tmi??

I'm already 5 days late on my period. I have no sign of her visiting me. My CM is like white and creamy. The past 2 says I've broken down and cried over the dumbest things, I don't think about early symptoms because, well, it's been 4 years since I've had a child and I don't remember if I had any symptoms with him other than I was this late.

Is it too early to test
