I know you said that your period is six days late, but it has to have been at least fourteen days from the last time you had sex, otherwise it is going to say negative no matter what. If you are really worried about it, you can wait another week and take another test, or you can go to your doctors and have a blood test done. Plus blood tests are much more accurate and you are going to have to get it confirmed by a doctor anyways if you are pregnant. So either you can wait another week or go to the doctors.
