Your odds of having twins with high hcg levels are certainly better than the odds of having twins with low hcg levels, but I don't think there's any definitive "you have a 50% chance of having twins" kind of information based on hcg levels alone. If you've undergone fertility treatment, or have a history of twins in your family, then high hcg levels are an indicator that you could be having twins.
Are you compltely sure of your date of conception? Even being one day off makes a big difference in this situation. I definitely wouldn't read too much into the levels regardless.
Like I said before, my level last time was 405 on 14 dpo with twins, and I was convinced I was having twins because of it (I had also taken clomid, and just had a feeling that I would conceive twins). This time, my level was 237 at 13 dpo, and 1037 at 16 dpo (doubling rate of 30.9 hours, so would have been a little less than 2000 at 17 dpo), and I again suspected twins, but I'm just having one baby. Perhaps this baby implanted early, or maybe I'm just a super hcg maker!
If you suspect twins, you can have an early u/s (twins should show by 6 weeks).
