Hcg at 4w 6d

at 4 weeks 6 days my HCG was 8730 I am currently 5 weeks 6 days I see a lot of people's HCG levels at 4 weeks 6 days and they're nowhere near as high as mine I'm hoping and praying I have a healthy pregnancy but I was just wondering are these signs of twins or is there anybody else with there HCG levels this high so early on in pregnancy please post your results so I can be a little bit more calm fear of carrying twins yiks in the name of Jesus whatever it is his will be done
