Implantation bleeding: Normal in early pregnancy?
Medically reviewed by Drugs.com. Last updated on Apr 29, 2021.
Implantation bleeding — typically defined as a small amount of light spotting or bleeding that occurs about 10 to 14 days after conception — is normal.
Implantation bleeding is thought to happen when the fertilized egg attaches to the lining of the uterus. Implantation bleeding usually occurs around the time you would expect to have a menstrual period. However, implantation bleeding is lighter than menstrual bleeding.
Some women don't experience implantation bleeding and others don't notice it. It's also possible to mistake implantation bleeding for a light period. If this happens, you might not realize that you're pregnant — which can lead to mistakes when determining a baby's due date.
Implantation bleeding is light, stops on its own and doesn't require treatment. If you're concerned about any vaginal bleeding or vaginal bleeding during pregnancy, contact your health care provider.
