Hi I have been using a period tracker to track my periods and they normally range between 26-28 days. My period was 4 days late this month being (32) days and then I began to have a light bleeding which goes to moderate. It went from pink to a bright red and watery. I have not had any clots. This is day 2 of this. My cramps are on and off and range from really light to strong. What could this be?
