I have been using Nuva ring for only one cycle and I will never use it again!! At first I used it and I was spotting for 5 days than * day s later I started bleeding heavily for 10days and counting now! I thought I was having a miscarraige!! Crazy cloting... intolerable cramps... mood swings... consistantly tired!!! I advise everyone to try things for themselves but I wouldnt recommend NR to anyone! if you cant take a pill everyday you might wanna try condoms or abstinance!!! Good luck ladies! AJ, from NYC/ATL
