Hi , I'm just wondering if I could be pregnant ... I missed my period in April . It was due on the 13th but it wasn't . I started bleeding lightly on the 25th , it lasted 2 days . I've had symptons of pregnancy , urinating a lot , eating has changed , head aches , back aches , nause . But every pregnancy test I do comes up negative . I've never been iruglar with my period . Could I be pregnant?
