Hcg results! Help! Twins?

Nancy • 9 year relationship, a beautiful 6 year old boy. One 5 month miscarriage 2 years ago. Finally trying for healthy baby #2
So I went to the doctor yesterday. It was exactly a month from my last period. I am pregnant but the doctor couldn't see the sac or anything because he said I'm only about 2-3 weeks so it's early. And also that he couldn't rule out miscarriage or ectopic. So I had my hcg levels checked and then again this Saturday coming up. I was so nervous they would be low and I would miscarry again. To my surprise they're higher than the chart even says they should be! Like double! I'm at 980. Can I be having twins? Can you ladies be kind enough to post your hcg levels and how far along were you? So I can get an idea.
