Give me your options


So today is day 5 of feeling dizzy and I’ve had headaches on an off, my breast have been sore, and now I’m officially one day late of my period. It would be baby number two I really feel like I’m pregnant. I’ve taken many of the 88 cent test from Walmart and they’re all negative. Should I buy a better test or wait it out see if I do start my period because it’s only been one day.
