I've been having unprotected sex with my fiancé, i still haven't gotten pregnant. I've gone to the doctor not long ago the test came out negitive. I'm getting really concerned. I've been on my period for two weeks now it's never happened to me before. What does that mean ? I've gone to the doctor for my nipples burning & having a lot of Breast pain the doctor thought I was pregnant so he made me take a test it still came out negitive he did a urine & blood pregnancy test & still came out negitive.
