High hcg, twins?


My HCG was 14000 then retested in 48 hours it went up to 28000. I did an ultra sound and i just seen 1 gestational sac with no yolk.

According to my period i am 6 weeks but i am probably 5 weeks or less since my period is always late

Anyone has high hcg with just one baby? Or did you have twins?

When can find out if they’re twins?
