What if my hCG levels aren doubling every 2 to 3 days from a quantitative blood test?
Don’t worry, it doesn’t necessarily mean something is wrong. Still, your doctor will want to perform an early ultrasound because slow-rising hCG can be related to impending miscarriage or ectopic pregnancy. On average, hCG levels double every two days from 4 to 6 weeks, then every three days, and finally slowing to every four days. Levels peak near the end of the first trimester, and it isn’t until the second trimester that hCG levels start to decline.
