Any multiples out there??

Interested in knowing your hcg levels. My dad is a twin and twins run thick on both of my parents sides..fraternal and skip generations. Everyone keeps saying they think I'm having twins. Only 6 weeks this week... But would love to know your levels. 
Here are mine. 
10dpo - 27
15dpo- 399
20dpo- 6123
Not sure if that's high or not, but I did see this twin hcg chart that made me wonder...
