Further along than you originally thought?

Wondering how common it is to be further along than you thought (i.e. Had a period your first month being pregnant) I've been feeling further along than 6 weeks 2 days all day, my mom made a comment that my levels were high at 4 Weeks 5 days. So I did math, if my levels doubled every 48 hours then tomorrow they'd be on the high end of 227,000.
