Ladies please help 😢

Just to clarify I will be seeing my Dr next week. Okay so I had my "period" 10-13. It came 4 days early. It was brown but filled a pad the first day so I genuinely thought it was my period. It lasted 3 days. (I'm being generous with the 3rd day.) Anyway, something told me to test today. I did on a digital It came back "pregnant." I took another one and it said "not pregnant." Has anybody gotten a false positive on the clear blue? Or do you have any other insight? Anything will be helpful 🥰
