Around one third of pregnant women experience some degree of implantation bleeding. Implantation bleeding occurs as a result of the fertilized egg attaching itself to the lining of the uterus. This type of bleeding is generally very light and typically takes place around ten to fourteen days (although some sources say between six to twelve days) after conception. Many women have questions as to whether or not they can prevent implantation bleeding, and about whether or not it presents a danger to the pregnancy. Here we try to answer some of these questions and concerns.
What Exactly Happens During Implantation Bleeding?
After a female’s egg is fertilized, it becomes a little ball of cells known as a blastocyst. This is what eventually becomes the embryo and develops into the fetus, or baby. As this fertilized egg, or blastocyst, makes its way down the Fallopian tubes and into the uterus, it needs to find the perfect spot to settle into for the next nine months of pregnancy. The blastocyst also has an outer layer of cells that provide nutrients to the developing embryo and will later on become a part of the placenta, known as the trophoblast tissue. As this trophoblast tissue burrows into the mother’s uterus, it may damage a few blood vessels in the uterus which causes a small amount of blood to leak from the cervix, which later exits through the mother’s vagina. This is that blood which you see during implantation bleeding.
