Not every test is always going to come positive.. My advice is that you wait another week take the test again.. No need to test every day and waste your money. But test in a week see what happens.. If you still didn't start your period and the test still says negative you may need to go to the doctors and have them run a blood test. That would be more accurate than the pee test any way.
