I am REALLY confused

Alright so I just had my period like last week it was a little shorter than normal but was normal heaviness AND I am on birth control

I found this test while cleaning out my bathroom and decided to take it because I couldn’t stop peeing and why not.

well, I wasn’t expecting this and it literally makes no sense??? AT ALL!! I have had unprotected sex but the timing of just having my period (?) is what doesn’t make sense

It is pink and came up within the time frame and everything. But then I used a clear blue in the same urine

The clear blue is completely negative. So is it possible the first response is just a false positive?? It is really dark to be an indent

Also neither test was expired
