There are many kinds of birth control out there, so don't let not being able to be on the pill stop you. What about an IUD without hormones, such as Paraguard?

Wait until it's time for your next period and see if you get it. If you don't, go ahead and take a home pregnancy test. But, honestly, since it was only the day after your period when you had sex, I doubt you have to worry. I mean, it's possible you're pregnant, but I doubt that you are. Just try not to worry until you either get your next period or are able to test.
