Whats implantation bleeding?

Question

What is it? and how do you know you have it? does it mean your pregnant?

Answer 1

Implantation bleeding can happen at the time the fertilized egg implants in the uterus, on average between 6 to 12 days past ovulation. It is is vaginal discharge which usually contains a small amount of pinkish or brownish blood. Only about 1 in 3 pregnant women experience implantation bleeding.
Approximately one third of all pregnant women report bleeding that is associated with implantation. The presence of implantation bleeding does not increase the overall risk of miscarriage, however. Most pregnancies will continue until term without further bleeding.

Report any abnormal vaginal bleeding during pregnancy to your doctor. Be prepared to give information about the amount of blood lost and a description of how you are feeling overall.

The cells that eventually form the placenta are called trophoblasts. Specialized trophoblasts, the syncitiotroblast, are responsible for developing an interface with the maternal circulatory system to provide nutrients and allow gas (oxygen and carbon dioxide) exchange to occur.

Sometimes, while this interface is developed, some of the maternal blood is lost. This implantation bleeding is typically short in duration and quite light. Implantation bleeding is one of the early signs of pregnancy.

Answer 2

Implantation bleeding sometimes occurs when an embryo initially embeds itself (attaches) in the uterine lining. Not every woman experiences it. It is usually just a bit of pink "spotting".

Yes, you have to be pregnant to experience implantation bleeding.
