Hcg levels at 5 weeks??

To make a long story short. My country does not offer betas but due to my worries (see my endless posts) I ordered via private lab that does NOT include doctors opinion a blood hcg that was 10445 IU/L at 5+2 (around 15:00) and then due to symtoms vanishing another at 5+5 (around 11:00) today which was 18469 IU/L.. is this an okay doubling time? Its not 48 hours but I know it can slow down slightly

Since I dont get any help from doctors or experts in Sweden, can redditers help me with your experience? I have a viability US at 6+5 and want to be mentally prepared.
