Can you have a positive pregnancy test and miscarry?

Yes, it is possible to experience a positive pregnancy test and subsequently have a miscarriage. A positive pregnancy test indicates the presence of the hormone human chorionic gonadotropin (hCG) in the urine or blood, which is produced by the developing placenta during pregnancy. However, a positive test result does not guarantee a successful pregnancy.

A miscarriage refers to the loss of a pregnancy before the 20th week of gestation. It is a common occurrence, affecting approximately 10-20% of all clinically recognized pregnancies. Miscarriages can happen at any stage of pregnancy, but are more common in the first trimester.

After a positive pregnancy test, the levels of hCG typically rise rapidly in early pregnancy. However, in the event of a miscarriage, the levels of hCG start to decline, leading to a decrease or absence of the pregnancy hormone in the urine or blood. This decline can be detected by repeat pregnancy tests, which may show a lighter or negative result over time.

In addition, certain medical conditions or external factors can cause the body to produce hCG, even in the absence of a developing pregnancy. These conditions include certain types of tumors, recent pregnancy loss, or the use of certain medications. In such cases, a positive pregnancy test does not necessarily indicate a viable pregnancy.

Therefore, while a positive pregnancy test is an indication of pregnancy, it does not guarantee its continuation. It is important for women who experience a positive pregnancy test to receive regular medical care and monitoring to assess the progress of their pregnancy and address any potential concerns.
