BFN but confused with symptoms. help!!

I'm 5 days away from my  AF to come I couldn't wait and I toook this dollar store test but after the BFN I saw that the test is best the day of the expected period 😐😒😞. I fee bloated, tingling sensation in my uterus, gassy, nauseous, dizzy, and I love coffee but I can't stand it, the only thing I found weird is that my period is supposed to come soon and my boobs are not sore as it's usually by this time. Am I going crazy? Should I get a more expensive brand?
