During the first 6 weeks, how does HCG change?

• A. Doubles
• B. Triples
• C. Quadruples
• D. Remains the same

Answer: (A)

In early pregnancy, hCG rises very quickly, following an exponential pattern. In the first six weeks, levels typically double about every 48 hours. This rapid increase helps support the corpus luteum and progesterone production as the placenta develops. Because of this swift rise, the description of doubling best fits what usually happens during this period. A tripling or quadrupling would imply a faster rise than is commonly seen, and remaining the same would not reflect the normal early increase.
