Am I pregnant?

So me and my bf went to six flags this past weekend. Anywhoooo we ended up having sex in our car. Hot and heavy. As we are doing the deed he doesn't have anywhere to release. We are clean freaks so he couldn't cum in the car. If he did I would be mad for DAYS. SO instead he came inside of me not a lot bc he had masturbated before we left to six flags. We ended up going to Dave and Busters afterwards. We were in the mood again. And the same thing happened but this time he ate me out so there was no mess in the car. I am really really worried. It isn't time for my period yet. I still have two weeks to go.

Should I be worried? What should I do?
