Equate brand of first response??

Kate
Stupid me accidentally grabbed the off brand test and didn't realize until I already opened the test (it wasn't the curved handle) I decided well I'll give it a shot anyway (would have dipped it but had to go bad lol) and I peed on the screen and the whole thing turned blue. Should I wait until I have to use the bathroom again or just say forget it and wait until Friday? Friday would be my last day of my period if it arrived when it should have, but still no AF
