For those of you who had a blood test and ended up having a chemical, how much was your hcg level?

After I had a faint line on 9dpo I did a blood test on 12 dpo that was 34mui/ml. I keep reading it’s low and probably a chemical. I tried testing again, lines are still there but not getting darker. I’m on holiday so can’t do a blood test until I’m back in a week so meanwhile I’m freaking out!!
