Pregnancy symptoms?

I know the only way to determine if I'm pregnant is a test. But I'd rather have opinions also. So I took birth control for a couple of months to regulate my cycle and it did. And I've been off of it for about 3 months and I had regular period. But now my period is 2 weeks late, I pee a lot, I'm nauseous like everyday, I'm always tired, my boobs kinda hurt and I'm so emotional. I don't know what's going on. I don't usually get like this before my period.
