At 5 weeks pregnant, hCG levels can range from about 19 to 7,340 mIU/mL. However, its important to note that hCG levels can vary widely from person to person and even from pregnancy to pregnancy. The American Pregnancy Association provides a general guideline for hCG levels during pregnancy, but its important to remember that every pregnancy is different. Here is a general guideline of hCG levels by week:

• 4 weeks after the last menstrual period (LMP): 0 to 750 mIU/mL
• 5 weeks after the LMP: 200 to 7,000 mIU/mL
• 6 weeks after the LMP: 1,080 to 56,500 mIU/mL
• 7-8 weeks after the LMP: 7,650 to 229,000 mIU/mL
• 9-12 weeks after the LMP: 25,700 to 288,000 mIU/mL
• 13-16 weeks after the LMP: 13,300 to 254,000 mIU/mL
• 17-24 weeks after the LMP: 4,060 to 165,400 mIU/mL
• 25-40 weeks after the LMP: 3,640 to 117,000 mIU/mL

Its important to note that hCG levels can vary widely and that a single hCG measurement is not enough to determine the health of a pregnancy. Doctors will typically monitor hCG levels over time to ensure that they are rising appropriately.
