I found this on a website. This is for singleton pregnancies.

* At 14 DPO, the average HCG level is 48 mIU/ml, with a typical range of 17-119 mIU/ml.
* At 15 DPO, the average HCG level is 59 mIU/ml, with a typical range of 17-147 mIU/ml.
* At 16 DPO, the average HCG level is 95 mIU/ml, with a typical range of 33-223 mIU/ml.
* At 17 DPO, the average HCG level is 132 mIU/ml, with a typical range of 17-429 mIU/ml.
* At 18 DPO, the average HCG level is 292 mIU/ml, with a typical range of 70-758 mIU/ml.
* At 19 DPO, the average HCG level is 303 mIU/ml, with a typical range of 111-514 mIU/ml.
* At 20 DPO, the average HCG level is 522 mIU/ml, with a typical range of 135-1690 mIU/ml.
* At 21 DPO, the average HCG level is 1061 mIU/ml, with a typical range of 324-4130 mIU/ml.
* At 22 DPO, the average HCG level is 1287 mIU/ml, with a typical range of 185-3279 mIU/ml.
* At 23 DPO, the average HCG level is 2034 mIU/ml, with a typical range of 506-4660 mIU/ml.
* At 24 DPO, the average HCG level is 2637 mIU/ml, with a typical range of 540-10,000 mIU/ml.

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
* Non-pregnant females: <5.0 mIU/ml
* Postmenopausal females: <9.5 mIU/ml
