I already started a post on this topic, so let it suffice to say that the seven days of uncleanness restore power to women over their conjugal relationships, and they protect women from vile abuses. In return for power and protection, a woman must count for herself seven days. Oh, the humanity! What severity of judgment! Count to seven? How dastardly! Compare that to the Torah’s view of men, who can become unclean from a number of things and must bathe themselves and wash their clothes whenever they do, and I think you will see that women have the upper hand in terms of cleanness and uncleanness in the Torah.
