Hi I'm 21 and my period was 2weeks late but I never had that heppen before so I took a year and it said negative but people saying that I am but I feel way more sleepy,I threw up for 2 days in a row,my feet be killing me every time I work or walk someplace far, I lose breath not like before, I be having stomach pain, I would be hungry a lot more I don't know if I'm pregnant I'm thinking that I am but I don't know what to do?
