Answer 4

It doesn't.  Just the pressure difference of being in a much greater density makes it appear that way.  If you stayed in water for the 3-5 days you had a period....you would still have a period.

Answer 5

For me it doesn't. I continues-and i never take baths when i have periods becuase that is gross to me. I take showers and even when i've taken both showers and baths it never ever stops.

Answer 6

It doesn't stop it is just diluted by the water so you don't really notice it.  

Answer 7
