I am totally freaking out about this! Anyone want to help me out?

Yes, you could be pregnant but there is no way to tell if you are.

You are having unprotected sex and that is the best way to get pregnant... it's kind of how the whole reproductive thing works.

Any time there is penile insertion there is the risk of pregnancy. You can minimize the risk, but not eliminate it.

You will have to wait until about 2 weeks after your next period is due.

And if the possibility of pregnancy freaks you out, then keep your legs closed.
