Has anyone received false positives from MULTIPLE brands of otc pregnancy tests?

I tested positive FRER, FR digital, FR rapid response, Clear Blue Digital, and dip tests. 😭

I made a trip to the ER when I started spotting and then heavily bleeding today.

They did urine, blood, and US tests and just told me their urine test was NEGATIVE?! HCG 15 from blood tests.

I am so confused and devastated. Has anyone else gotten multiple false positives?! I feel insane. 😔😢
