I just need some advice .. I posted anonymously because I am embarrassed . Me and my boyfriend had unprotected sex last night for a few minutes after I gave him head and swallowed . He did not cum inside of me or at all . I am worried about getting pregnant now , but was lost in the moment at the time . I am 17 and still live with my mom and she is very against sex before marriage and would freak if she knew . I have tried to talk to her about birth control before and she grounded me from seeing my friends and took away my phone for three months so telling her or running to the store and getting plan B isn't really an option for me because she can see where I spend my money on my card and I currently have no cash . My period is supposed to start on Friday, and if I get it , does that mean I am not pregnant ? Or is it too soon ?
