HCG levels?

Lauren

Hey guys. So I got a blood test two weeks ago on 7-17 and my hcg was 42 (2 days before my missed period). Two weeks later on 7-31 I got another blood test and my HCG is 22,376. My doctor wants me to come in for a sono on Monday instead of Wednesday. What are your thoughts? I’m of course thinking either it could be normal, multiples or possibly something bad? Thanks guys!
