hCG levels seem okay?

I first had my hCG tested at about 3 weeks 5 days, I went yesterday to have it tested again- I’m currently about 6 weeks 3 days.

April 7th: 3 weeks 5 days- hCG was 27

April 24th: 6 weeks 2 days- hCG was 18,902

Seem like appropriate numbers? By doing the math it seems like it at least doubles every 48 hours.

I know you’re supposed to take them 48 hours apart. I just haven’t had many symptoms and needed some reassurance, so I had my numbers drawn again.

I see some others with way higher numbers so wanted to check.
