sex for the first time

So I had sex with my boyfriend for the first time almost two weeks ago. Like it was my first time ever. So it wasn't great but he made it enjoyable for me. Anyway. I figured I'm not the only girl to ever loose her virginity and then assume she's pregnant. We used a condom but I'm not on birth control. I guess I'm just looking for some reassurance. Ik you can't tell me 100% that I'm not pregnant I just need a little encouragement and for someone to tell me everything's alright. My period is still two weeks away so I'm not even late. I just am kinda freaking out bc ya know I'd never had sex before. So if you have something kind and encouraging to say I could really use it right now. Thanks everyone!!
