Implantation bleeding

From Wikipedia, the free encyclopedia

Implantation bleeding is a small amount of vaginal bleeding that can occur in early pregnancy due to the fertilized egg attaching to the inside of the uterus.[1]Implantation bleeding occurs between 7 to 14 days after fertilization.[2][3]Implantation bleeding may be accompanied by symptoms such as cramping, nausea, breast tenderness, and headaches.[4]Implantation bleeding can be distinguished from period bleeding by color, clotting, strength of flow, and length of flow.[5][6]

However, there is no support for the notion that implantation produces vaginal bleeding.[7] Bleeding and spotting are common during the luteal phase of the menstrual cycle as well as during early pregnancy, and for reasons unrelated to implantation.
