Am I just paranoid..?

Okay my period is supposed to happen next week monday, and I had sex about two weeks ago. I'm on birth control, and A condom and spermicide was used, but I was late on two pills, not missed though.

So far, I've been peeing a lot. That's it. And I don't even pee. It just feels like I have to pee but nothing really comes out. No sore boobs, no fatigue, no nausea, just peeing. And it's really irritating. Am I just being paranoid about being pregnant?
