The blood lost during menstruation comes from the uterine lining that had built-up over the coarse of the woman's menstrual cycle, it doesn't come from a womans main blood supply. As long as a woman is healthy there is no loss from menstruation, and nothing needs to be done to 'recover' anything.
It is normal to have minimal bruising during menstruation. Decreased estrogen levels during menstruation cause a loss of the blood vessel's elasticity in the body. This can cause small leaks that can turn into small bruises. Anything more serious or that last past the cycle should be looked at by a doctor.
No it does not.
There is no proper reason why the women are considered impure for menstruation. The belief came from mere anxiety probably. The belief seem to have evolved in various cultures, almost simultaneously, probably. There is nothing impure in the menstruation.
You can do absolutely anything you like during menstruation - there is absolutely nothing that you can't do on your period.
