Hello, My daughter is 10 years old with 5.2" height and 52 Kgs. She is matured in the month of May 2015. From than she has a very high bleeding during menstruation. She needs to change 3-5XL pads during first 4 days. She is learning karate (thrice a week). Which is the only exercise apart from school activities. I have endometriosis problem and was operated 4 years back and in treatment of marina coil now. My doubt, is my daughter problem is common at this stage or this due to exercises she does in karate class (hardly any one day during periods). Or is it any way related to my endometriosis problem? (As genetic disorder) I am in dilema what to do. Please suggest. Thanks in Advance. Srilatha.
