My daughter’s period is very heavy this month. (As in tampon changes every 15-30 minutes for 2 days) I don’t understand where all this blood is coming from. Has it collected in her lining over the course of the cycle, or is it coming from blood directly in her circulatory system? The doctor is more concerned with anemia than blood loss, but I’m a mom, I can’t help but worry! Thanks for all replies!
