Hi... Yesterday, I had unprotected sex with my boyfriend. He just told me that he things he might have cum in  me a bit... I know that he didn't cum everything in me because I saw it with my own eyes but he told me he wasn't sure if he did or did not cum in me and he didn't want to take a chance and obviously me neither... Can you become pregnant of he only cum a bit? I dont know What to do... Im so stressed right now... Im only 15 years old and I do not want to be pregnant... I was thinking about a pill that cleans everything in your body, but I don't even know how it's called, I don't know how it cost, I don't know what are the side affects either ( and I don't want my parents to know...) and I don't even know how it looks like :(!! Please someone help me...
