How to Know About hCG Levels in Early Pregnancy?


One of the most important signs that help to detect the pregnancy is hCG hormone levels. But during early pregnancy stages, most women wonder about the hCG levels. Usually, hCG levels in a normal pregnancy exist in the range of 1,200 mIU/ml. This level doubles for every 48-72 hours, which increases by up to 60% for every 2 days.

So, most of the women are confused with how these hCG levels can be recognized during early pregnancy stage. Most of the times, pregnancy test results and pregnancy symptoms will depend on how high or low the levels of hCG. The higher the hCG levels, the higher are the symptoms of pregnancy.

Usually, pregnancy can be detected by missed period, implantation bleeding, positive pregnancy test or other typical signs of pregnancy. Pregnancy hormone hCG has a wide range of normal levels during the early pregnancy. hCG hormone is nothing but “Human Chorionic Gonadotropin”, which is produced by the placenta after the implantation takes place and it usually happens one week after fertilization and ovulation. Then the hCG levels will continue to increase until 10-12 weeks where it will stabilize or go down.

Here are the hCG levels in a normal pregnant woman:

hCG hormone levels

  • hCG levels less than 5 mIU/ml can be thought as “not pregnant”.
  • hCG levels greater than 25 mIU/ml can be thought as “pregnant”.
  • hCG levels between 5-25 mIU/ml need a follow-up checkup to know whether you are pregnant or not.
  • During early pregnancy, hCG levels are below 1,200 mIU/ml and those levels double for every 48-72 hours. Usually, those levels will increase by at least 60% for every 2 days.
  • If the hCG levels are in between 1,200 and 6,000 mIU/ml during your early pregnancy, then it will take 72-96 hours to double.
  • hCG levels above 6,000 mIU/ml can take more than 4 days to get double.
  • If you enter into 9 or 10 weeks of your pregnancy, the hCG levels start decreasing.

Frankly speaking, there is no single normal level for hCG hormone during the early pregnancy and with the progression of your pregnancy, these levels will vary greatly. Most women will also have low hCG levels, which means you have miscalculated your conception date or you may have an ectopic pregnancy or you are at the risk of miscarriage. But don’t worry, even women with low hCG levels can have a perfectly healthy pregnancy.
