what was your hcg level at about 4 weeks?

i miscarried nov 7th and my hcg was 3 on december 1st, which she considered to be a complete miscarriage. i just got a positive test yesterday morning (12/11) and my hcg was already 600? does that seems really high really fast? obviously i’m pregnant so i’m not worried about that but just seems a bit high lol

(my mom is a twin, so that’s why i ask, not sure if maybe this correlates and could be twins)
