Hello Ajdec,
Don't worry, our beta numbers are different because yes, they will differ from individual to individual but remember you are 1 day ahead of me and that can make a BIG difference. The reason is because our beta numbers are supposed to double every two days. My first beta of 152 was done 3 days before you took yours and 2 days before my original scheduled beta test date. And, I know you just took a beta on Mondays as I did also and your numbers were 9700 and mine was 6245. If you think about it, I am one day behind so if I would have taken my beta on Tuesday, my numbers should have been 9367, which is not far from yours and actually that would have been the same day after ET as you. So long story short don't worry. I am sure everything is fine. The normal levels of HCG are posted below:
