Hi I'm 17 years old . I'm sexually active . I'm scared & don't know if I'm pregnant or not . My last period was around June 28& I was suppose to get it last month in July but I didn't get it & it's already August . I had unprotected sex with my boyfriend . But we're always careful . We've been sexually active mostly 2 years now but never had this happened before & never used a condom during that time.. Maybe just once this has happened . But it's happening again& not sure if I'm pregnant . Do you think I'm pregnant ? I don't know what to do . Please help!
