HCG Levels

Hi January Mommies!! 
I went in at 6 weeks to get my pregnancy confirmed and hCG levels tested. They were about 60,000. Now I think I might have been 7 weeks but is that still a high number?? I know it varies from pregnancy to pregnancy but I can't shake the feeling that I might be having TWINS. I'd love to hear what everyone else's levels were at about 6 weeks, espececially mommies expecting more than one! 
Happy pregnancy<3
