anytime that you have unprotected sex and are not using any form of contraception you are at risk to getting pregnant. why did you have sex with your boyfriend without a condom? had he worn one you would not be freaking out right now. if you start showing any signs of pregnancy you will need to do a home pregnancy test or see your medical provider for an examination.
