I am 26 female. I want to ask that my periods are always light and lasts for 3 to 4 days. From 5 or 6 months they become more short. Like 2 days only. And i am having cramps backache from 3 months. And most of the blood passed in urine instead of filling the pad.my blood test, urine test, pelvic ultrasound allare fine.
Is this normal flow of blood?
