I am single with a 26 day cycle of menstruation which is very painful. A brown discharge persists for a week (like clots or flexible layers) for 6 days subsequent to my 5-7 days cycle. Quantity is quite significant. On a couple of occasions my first day before periods sees a similar situation. What is the reason? At present have been prescibed Susten 200 for 10 days and see the consequences. Tomorrow will be the 10th day of Susten 200.
