First Ultrasound & high HCG levels

Breanne
So my levels indicated that I was about 6 weeks pregnant (46000) which I knew wasn't right.. we could see only the sack and yolk, no fetus. So we're estimating I'm about 4-5 weeks along. The nurse assured me that HCG levels vary from each woman but aren't my levels a little high for being so early? And if it were twins, clearly I would've seen two yolks today? 
Anyway, I find out Monday if the pain in my abdomen is my gallbladder or not, but good news is that I'm not ectopic!! 😊
