HCG Level

I just got the results from my 2nd hcg blood test. The first test I took came back at 612 and the 2nd 7 days later came back at 10,555. Does that seem high? We did an ultrasound last Thursday and can only see one sac but we cant see the heartbeat just yet. Dr. says its still to soon. Has any one else had numbers jump up this fast?

since hcg doubles every 24-48 hours, you are within normal. Technically, they could be even higher if yours happen to double every 24 hours. Looks like your are double maybe every 36 hours or so...
ex:
day 1- 612
day 2- 1200
day 3- 2400
day 4- 4800
day 5- 9600
day 6- 19200
etc....

how far along are you? that seems like great doubling time to me! i just went back for my 3rd set of labs (i am around 6w / 27dpo) & am now at 23,700 from 2,000 a week ago, so I think my doubling time is around 48hrs...at least my doc finally okayed me to go for my first u/s on Monday =)
