So on January 24th 2015 , me and my bf were rubbing our genitals together (naked) and he didn't prec.. nor cummed then he wanted to try to put it in and he put on a condom . And it wouldnot fit. So I ovulated 2 weeks ago a cording to an app , and my period should be here in 7 more days , I took two pregnancy test and came back negative . I've noticed my boobs changed colors and hurt on and.off . Can.I be pregnant ?
