Implantation bleeding is defined as a vaginal discharge, characterized by pinkish or light brown-colored blood. Many clinicians regard implantation bleeding as being one of the earliest signs of pregnancy, as it typically takes place anywhere between 6 to 12 days after fertilization. So what can we qualify as “normal”, when implantation bleeding begins? It is commonly understood, that some degree of bloody discharge is to be expected, but when should you start worrying?
The Basics of Implantation Bleeding
One of the best ways to identify, when something is abnormal, is to clearly define the parameters of the “normal” process. One thing to remember is that implantation bleeding is a relatively common occurrence – roughly 30-33% of all women, who conceive, experience this condition. It takes place when the fertilized egg (we can also call it “blastocyst”) makes its way down the Fallopian tube and attaches itself to the lining of the uterus. As the embryo begins adjusting itself to its new “home”, several layers of tissue collectively referred to as the “trophoblast” begin to form around the so-called conceptus. This can rupture localized blood vessels, which in turn can cause light bleeding. This discharge typically appears around the same time of a woman’s normal menstrual period. Implantation bleeding is usually lighter, and it normally lasts for a short period of time. Bloody discharge during egg attachment will stop on its own, and it typically does not require any special treatment.
