Ooof trying to hold to test...

So my period is supposed to start today but nothing to far. I've been checking my CM and all is regular (I've heard that you can get a brownish discharge or something when your period is about to start idk if that's true but I did it anyways)

I do cramp a little if I touch my cervix but it goes away if that means anything lol

I wanna wait to test for a couple days, thoughts?
