How long after delivery will pregnancy test be positive?

Pregnancy tests detect the presence of human chorionic gonadotropin (hCG) in the urine or blood. hCG is a hormone produced by the placenta during pregnancy. After delivery, the placenta is expelled from the uterus, and hCG levels drop rapidly. Therefore, a pregnancy test will typically be negative within a few days to a week after delivery.

However, hCG levels can sometimes remain elevated for a longer period of time, especially after a miscarriage or an ectopic pregnancy. In these cases, a pregnancy test may continue to be positive for several weeks or even months after delivery.

If you are concerned about the results of a pregnancy test, it is important to talk to your doctor.
