First of all, relax. Freaking out doesn't solve anything. Secondly, you'll be happy to know you wouldn't have a single solitary pregnancy symptom within 2 days. It takes at least 2 weeks. So whatever you are feeling is not related to pregnancy.

Now, why are you having risky unprotected sex? You should always use condoms at a minimum to protect yourself from sexually transmitted disease and pregnancy.

i dont know i really wanted to do it with him cuz i wanted it and we didnt have anything and so we just did it

Did you hope to become pregnant also? This is really risky behavior. Sounds like you didn't think it through very well.

Go to planned parenthood. Get birth control. This won't be an issue again.

Like Ingi said, this pain in unrelated to pregnancy. You won't know for another 2 weeks, until then your body won't even realize it is pregnant. And also like Ingi said, "want[ing] to do it with him cuz you want it" isn't a good enough reason to risk a pregnancy. Please invest in some birthcontrol (you may also get it for free!) and try to get planB if you're still within 72 hours. You don't want to get pregnant over some "heat of the moment" sex when you're not ready for a child.

yea i know and that was totally stupid of me. and you were right it was in the heat of the action and no im not ready to have kids in the first place.
