Please help I'm freaking out now

Idk where this post belongs but it seemed like the right place. Okay so me and my guy had sex yesterday for the first time without a condom and today in feeling sick and I'm lightweight panicking and I wanna know what symptoms are commons I know missed period and my period should start in a few days... and if I do end up pregnant I'm scared. I go to college and I'm a freshman and my parents will kick me out of the house. I've always wanted my own baby but I'm not ready honestly and I'm scared someone please 😭😭
