When I was 4w6d, my hcg was 18,762. I thought that was high, and according to online charts it is, but my OB said he's seen numbers all over the place and doesn't put much value on them for anything other than determining when a scan might show something. FWIW, I got a scan 7 days later and was dated 6w2d, so I suppose you could say I was 2 days further along; however, being high risk, I was scanned weekly until week 14 and I don't think I ever measured exactly 7 days from scan to scan.
Your number is good, but I really don't think you can tell anything from it. You could be further along, or not. Just hard to go by a number that can vary so widely from person to person and pregnancy to pregnancy. Congratulations!
