"Implantation Bleeding
Implantation bleeding can cause you some confusion when you are unsure whether or not you are pregnant. It is not always easy to tell what is break through bleeding, or spotting between periods, and what is actually implantation spotting. The difference between period and implantation bleeding is that implantation bleeding occurs as a result of the embryo burrowing into your endometrium. However, because implantation spotting usually occurs right around the time you would be expecting your period, it is easy to mistake it for your period or as breakthrough bleeding.

Implantation bleeding signs generally include blood that is lighter than menstrual bleeding and is either pink or brown in color. How long implantation bleeding lasts will vary from woman to woman. It is important to note, though, that spotting in early pregnancy is not the same as implantation bleeding. "
