Although it may be confused with menstrual flow, implantation bleeding can be easily distinguished, since it consists of a more fluid texture. Normally, its color on a pad or toilet paper looks pinkish or brownish. It is uncommon for implantation bleeding to be bright red, although it can occur in some cases, which leads many women to confuse it with their period. Normally, implantation bleeding lasts only a two to five days.
