If it settles down and stops bleeding, she can get up 24 hours after the
bleeding stops. Only if she
begins to lose blood at a rate of more than a maxi pad in an hour, or "floods" when she pees a whole lot of blood at once, or begins to feel dizzy or feverish, she should go to the ER. She shouldn't go to the ER for light bleeding or moderate bleeding only with peeing, she should go to bed.
