A pregnancy test will likely be negative 2 to 4 weeks after a miscarriage. This is the time it typically takes for pregnancy hormones to decline to undetectable levels.
Understanding hCG Levels After Miscarriage
After a miscarriage, your body still contains the pregnancy hormone human chorionic gonadotropin (hCG). A pregnancy test detects this hormone. It takes time for hCG levels to drop back to zero, which is why a test can remain positive even after the pregnancy has ended. Once the hCG hormone has fallen to a level which is not detected from a urine pregnancy test, your body will start the next menstrual cycle.
Factors Affecting hCG Decline
Several factors can influence how long hCG remains detectable:
- Gestational age at the time of miscarriage: Higher hCG levels are typically present in later stages of pregnancy. Therefore, a miscarriage occurring later in the pregnancy may result in a longer period for hCG to decline.
- Individual variation: Every woman's body processes hormones differently.
- Complete vs. Incomplete Miscarriage: In an incomplete miscarriage, some pregnancy tissue remains in the uterus, which can prolong hCG production.
Monitoring hCG Levels
In some cases, healthcare providers may recommend monitoring hCG levels with blood tests after a miscarriage to ensure they are declining appropriately. This is especially important if there were complications or if an ectopic pregnancy was suspected.
