Levels generally peak at around 8 to 14 weeks after conception. After that they decline somewhat, and usually plateau during the second and third trimester. Your hCG levels at any particular point in time during pregnancy don't mean much. Although there are average ranges of hCG levels for different stages of pregnancy, these can vary dramatically from woman to woman, and from pregnancy to pregnancy.
Even if your hCG levels are outside the "normal" range, you can still have a perfectly healthy pregnancy and baby. That said, it is important that your hCG levels increase during early pregnancy. If your hCG levels don't continue to rise rapidly during the first few weeks or if they start to drop, this can signal a problem such as an ectopic pregnancy or miscarriage.
Higher-than-typical hCG levels can signal that you're carrying multiples or, in rare cases, have a molar pregnancy. Often, you won't know what your hCG levels are during pregnancy. Home pregnancy tests don't give a specific hCG number.
However, you may learn your hCG levels if your provider orders a blood test to confirm your pregnancy or as part of a screening test. Your provider may also order a series of two or more hCG blood tests if he or she has concerns about how your pregnancy is progressing. These blood tests, taken two to three days apart, can tell your provider whether your hCG levels are trending in the right direction. While hCG levels can vary widely from person to person and from pregnancy to pregnancy, they tend to fall within a range.

Your doctor may want to check your hCG level in early pregnancy if you experience symptoms of a miscarriage, such as bleeding and cramping. Slow-rising hCG levels can also be a sign of an ectopic pregnancy. If your hCG level is high enough, ultrasounds can be used to detect a gestational sac and monitor fetal development. Everyone is different, and hCG levels can fluctuate without indicating a larger issue.
If your hCG levels aren't exactly doubling but are still increasing, that's a good sign. Because of these natural variations, hCG patterns alone cannot determine whether or not your pregnancy is viable. Hormone testing should always be followed up by an ultrasound before a diagnosis is made.
In the early weeks of pregnancy, hCG levels that decrease are more likely to indicate a miscarriage than those that increase at a slower rate. The hCG level tends to peak between weeks 8 and 11 of gestation. Once you enter the second trimester, hCG will level off and decline closer to the level it was back when you were just 6 to 8 weeks pregnant. Although it's tempting to read into every detail during the first few weeks of pregnancy, it's best to try and be patient for your first ultrasound appointment.
Increases in hCG are expected for a viable pregnancy, but this information must be viewed within the context of additional tests, signs, and symptoms.
Your doctor can help you decide which tests are best for you based on your individual medical history and concerns. Most pregnant women don't track their hCG, or human chorionic gonadotropin, levels unless they have undergone fertility treatment or are experiencing pregnancy complications. Produced by the growing placenta during pregnancy, hCG is the hormone that home pregnancy tests detect in the urine. With a home pregnancy test, all you get is a positive or negative result.
Blood tests, on the other hand, measure the actual amount of hCG present in the blood. Also know that there are many organizations that provide support for those who have experienced pregnancy loss. Talk to your doctor for more information.
