help hcg quantitive test

liah

i’ve been getting positives left and right, i went to the er (10/9) and my urine came back negative and beta hcg came back 21 mUl/mL. I went today due to cramping and bleeding and i was told my urine was still negative and my hcg levels were the same i looked at my chart and my hcg levels were 52mUl/mL i’m confused they said it’s coming back negative but clearly it’s says below 5 is not pregnant, between 5-24 is indeterminate, and over 25. i was told follow up with a obgyn some moms say their period came and was still positive i don’t think is get that many false positives

first test (10/09)

second test (10/12)
