No period and negative test.

My period is 5 days late. I took a test yesterday and it was negative and than before I went to bed a had I tiny dot of blood so I thought maybe my period would be here when I woke up but still nothing. I am kinda stressed out, I babysit three kids who are pretty bad so I have to yell at them constantly and their mother doesn't pay me so I stress about not getting paid a lot I'm getting even more stressed about my period not showing up. Should I take another test or wait it out?
