When to test?

When is the best time to test? I’m not currently trying to get pregnant nor am I preventing it either. My period is two days late. I don’t trust symptoms bc I know they could be period signs too, but I’ve been having on and off cramping that seems lower then usual, I get on and off pressure (not sure if that’s the right description) in my vag and butt (maybe It’s from being a little constipated??). On and off lower back pain. Also get nausea spells but are mostly triggered when I vape which isn’t normal for me. I’m debating on waiting to see if my period starts or just test and get it over with, but I don’t want to test and it be too early for an accurate result.
