So Confused (and worried and sad)

I got my first positive on Wednesday using a store brand equivalent to Clear Blue (the one that shows a plus it positive) and my second positive that same night with a Clear Blue digital.

Since then I’ve had 2 First Response, 4 cheap dollar store tests and another Clear Blue digital come back positive. I wasn’t able to get in to see my Doctor for many weeks so I went to a walk-in clinic. I was hoping to get sent for blood work to confirm and to see that the HCG is rising.

The pregnancy test at the clinic came back negative. She flat out told me I wasn’t pregnant. When I asked why I’ve been getting so many positive HPT, her response was “I don’t know”

She did send me for blood work to verify but I’m so scared/confused/worried.

Anyone insight?
