My cycles have always been anywhere from 25-31 days. Some months are heavy and some are not. In the past my periods would last anywhere from 3 days to 7 days. For the last 5 or 6 months my periods have been lasting about 10 days. This month so far I am on my 13 th day. I have just been spotting for the last 6 days but it is still bright red blood. I had my a child 9 months ago. I tried the Nuvaring for 1 full month and this is my second menstrual cyle since I stopped using it. My physician is out of the office for 2 weeks so I am looking for some answers to why my periods may have changed in length.
