HCG level at 15 dpo?

[lindsayms05]

Ok, so I asked my doctor if he could do bloodwork because I was repeatedly peeing on sticks and wanted some reassurance that everything was going fine. I had my blood draw yesterday at 15 dpo and the level came back at 82.7. I got my first positive test at 10 dpo on a frer. Should I be worried?? I know with my first pregnancy, my level was 240 at 14 dpo, although I did get a positive 2 days earlier that pregnancy so I must of implanted earlier. Ugh, any reassurance?
