This boy and I were messing around and my parents told me to stay away but I didn't listen and so we were in his room together and he didn't have a condom and I didn't care at the moment and so he tried too stick it in but it hurt so we stopped and now I'm really scared that I might be pregnant, my period isn't due for like another 18 days so should I just stop worrying or what..

You should stop worying you won't be pregnant
