Sarh I'm not sure if this will help but its a guide to hcg docs use that someone posted when i needed it last
Accordingly, the key to interpreting the true value of HCG measurements is to look at their progression. In general, the HCG level will double every two to three days in early pregnancy. Approximately 85 percent of normal pregnancies will have the HCG level double every 72 hours. However, as you get further along in your pregnancy and the HCG levels get higher, the expected doubling time increases.
For HCG levels 6000 mIU/ml, the expected doubling time is >96 hours.
HCG levels peak at about eight to 10 weeks of pregnancy and then decline, remaining at lower levels for the rest of the pregnancy. Here is a sample listing of expected HCG levels based on time after conception:
0-1 week: 0-50 mIU/ml
1-2 weeks: 40-300 mIU/ml
3-4 weeks: 500-6,000 mIU/ml
1-2 months: 5,000-200,000 mIU/ml
2-3 months: 10,000-100,000 mIU/ml
2nd trimester: 3,000-50,000 mIU/ml
3rd trimester: 1,000-50,000 mIU/ml
