How dark should a pregnancy test line be at 5 weeks?

5 weeks: 18 – 7,340 mIU/ml. 6 weeks: 1,080 – 56,500 mIU/ml. 7 – 8 weeks: 7,650 – 229,000 mIU/ml.

When does your hCG stop doubling?

After your hCG level passes 6,000 mIU/ml, it may take more than 4 days to double. You can usually expect your hCG level to stop rising between week eight and week 11 of pregnancy. That is the time period during which the hormone tends to reach its peak.
