Hcg levels start declining in the second and third trimester so I'm curious as to why you're doctor is expecting then to go up.
Here is some info:
HCG levels rise during the first 8 to 10 weeks of pregnancy then decline slowly for the second and third trimesters. The following presents some average expected HCG levels based on time after conception:
First 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
