HCG levels level out at which week?

• A. 16th
• B. 18th
• C. 20th
• D. 22nd

Answer: (B)

HCG behavior during pregnancy follows a clear trajectory: it rises rapidly in early pregnancy, roughly doubling every couple of days, peaks in the first trimester (around 8–11 weeks), and then levels off as placental function takes over. By the mid-second trimester, roughly around the 18th week, hCG production stabilizes and the levels remain relatively constant (with only gradual changes) for the remainder of the pregnancy. This plateau is why hCG is most helpful for dating and viability in early pregnancy, while later on it becomes less informative because the levels settle into a broad, steady range.
