Positive on Cheap Brand and Negative on Expensive??

Has anyone got a positive on a cheap test and a negative on a name brand using the same urine?

I got this which looks positive to me, I’ve never had an indent line like this if that’s what it is. (This was taken at exactly 5 minutes which is what the box says)

So then I took a clear blue and it looked completely negative.

The app says my period isn’t supposed to start for another 6 days and if I am pregnant I would only be 4 weeks today.

Please help!
