I didn't get my birth control shot . I was schedule to get one Nov. 12 but I had to work so I couldn't make it . But before that like the end of October I got my period . Me and my boyfriend have been having sex . I should have got my period like the end of November but I didn't . And it still hasn't came yet and it's been over a month sense I had my period . Does this mean I'm pregnant ?? Please Help Me !
