Possibly pregnant 🤷🏾‍♀️

On Friday , I was over my boyfriend house and we had unprotected. He often pulled out though . He even ejaculated on my leg. But I’m scared because I haven’t missed my period or anything but I feel funny. I haven’t had any morning sickness or anything but I have been worried . My period comes on the 10th and right now I’m terrified it won’t come on. I’m only 15 . If I’m not pregnant I will never have unprotected sex again. I’ll even sit down and have a discussion with my mom about putting me on birth control. Anybody know what early pregnancy feels like? I’m worried
