A chemical pregnancy is an early miscarriage that occurs shortly after implantation. It is referred to as “chemical” because it is only identified by the presence of the hormone hCG (human chorionic gonadotropin) in the blood or urine, which is a "chemical" sign of pregnancy.
This type of pregnancy loss typically happens before the fifth week of pregnancy, often even before a woman realizes she is pregnant. In a chemical pregnancy, fertilization and implantation have indeed occurred. The embryo might even begin to secrete hCG, resulting in a positive pregnancy test.
However, development ceases soon after, and no gestational sac or fetal heartbeat can be seen on an ultrasound. This is why most women who experience a chemical pregnancy confuse it with a slightly delayed menstrual period.

The precise reason behind chemical pregnancies is not always understood, but they typically occur due to chromosomal defects within the embryo. These defects lead to improper growth of the embryo.
The other causes of a chemical pregnancy include:
Chemical pregnancies are generally a natural consequence of issues with the embryo itself or the early stages of implantation.
Most women are unaware that they have experienced a chemical pregnancy unless they have taken an early pregnancy test. However, some potential signs and symptoms include:
In some cases, women may not experience any symptoms and will only discover their pregnancy and loss through standard early testing as part of fertility treatment.
A chemical pregnancy is typically diagnosed by:
Chemical pregnancies highlight the importance of monitoring early pregnancy, especially for individuals undergoing fertility treatments or those who have previously experienced pregnancy loss. Early blood testing to determine hCG levels can identify pregnancies that might otherwise go undetected.

The majority of women who experience a chemical pregnancy go on to have successful pregnancies. The occurrence of a chemical pregnancy might even indicate fertility, as it shows that fertilization and implantation can take place. If chemical pregnancies continue to happen, your physician may suggest additional tests to investigate any underlying issues.
A chemical pregnancy is an early miscarriage that occurs shortly after implantation. While it can be emotionally challenging, it is also quite normal and usually happens for reasons beyond control. Understanding what a chemical pregnancy is may help women make sense of early pregnancy loss and provide reassurance for future attempts at building their family.
