A small amount of spotting during the first weeks of pregnancy may actually be what is known as implantation bleeding. This slight amount of discharge occurs as a result of the fertilized egg attaching itself to the lining of the womb. Embryo becomes a ball of cells, known as a blastocyst. As the fertilized egg attaches, it can disturb the lining of the uterus. As a result a woman can experience a small amount of bleeding, which can last anywhere from a few hours to 2-3 days. The good news is that this is a common thing for 30% of pregnant women. Such a type of bleeding usually subsides with no further issues.
Normal Versus Abnormal
Normal implantation bleeding is just that, normal. It is simply an early sign, perhaps the earliest symptom, of pregnancy and is a proof that things are proceeding the way they are supposed to. The bleeding is typically very slight, less than a menstrual flow, and generally takes place about a week earlier than when the expected menstrual period would take place. The blood may also appear darker than a regular period, as this type of discharge has had to travel a ways before exiting through the vagina.
