I have been pretty regular for years, this month I was a week late when I finally started. I have been bleeding now for 12 days. normally I would have light bleeding for the first 2 days, then heavy for one day and then it would be gone by the 5th day. This have been fairly heavy for most of this 12+ days. In your opinion, should I wait to see if it stops on it's own or should I go see my DR. I don't take any birth control. Any advice would be great. Thanks for your time.
