I have a question about hcg 🤔

Chelsea • 21 y/o 🤘🏾 1 miscarriage 💔👶🏾 ttc 4ys

So I went to the hospital because I wasn’t feeling good and I had very faint line rest on several different brands I went to the hospital and they said no, but on my paper it’s says that my hcg was 0.5. Any other time it’ll be 0, would that be considered pregnant or mc or chemical pregnancy??
