The most common color for implantation spotting is pink or brownish, although the characteristics of this bleeding can vary from one woman to another.

However, the characteristics of implantation bleeding are different from menstruation, as it is usually not bright red and, furthermore, it lasts for a shorter time.

Implantation bleeding can be pink, a more reddish color, or even brown, depending on the woman. Generally, the color is not as intense as menstrual bleeding.
