Mine were high with my last DD, 70000 at 7 weeks, this time high at 5 weeks 1 day 15,812, haven't had them done since but think they will have been similar to yours again. According to Ob, some people just have higher HCG. Could be twins though (are you getting a sneak preview, dating scan soon?). It's only one for me, phew!
Apparently higher HCG more chance of a girl as well, though that is probably just one of those old wives tales.
Hope all going well,
take care
