Pregnant?

I've been off my birth control for over a month now. Me and my partner are very sexually active and we haven't used a condom. I'm two days late on my period and have noticed I've been peeing A LOT. I have other symptoms as well but some could be pms. I took a pregnancy test the day I was supposed to start and it came back negative, however I had drank a lot of coffee and soda and had peed quite a bit before I took it. I just found out you're supposed to wait until the morning to take it so your pee is more concentrated. I plan on taking another test in a week but I just can't stop thinking about being pregnant.
