Irregular or Belly?

First thing, I have not tested. I'm really not trying to get my hopes up but last week I was experiencing pains in my stomach and my back but was 8 days before AF. Now I get minor pains that comes and goes and im 2 days late. I've been nauseous and constipated. My stomach is a bit tight and when i press or feel around my pelvic area there's no normal pain or tightness that i usually feel when I get or am about to start AF. I know the first think people are gonna comment is test test test but it's like i'm terrified. I've been trying so long and i don't wanna get my hopes up so im trying to wait it out until I've missed my full period.
