Ive been on nuvaring for about 7 years and my periods are very consistent. However over the years it comes later and later. For example when I first started nuvaring, my period would start the wednesday after i removed it on sunday. Over the years it has moved all the way up to Sun. or even the next monday before I start my period. This cycle I removed my ring on Monday instead of Sunday (forgot). I thought I was starting my period that next sunday, as when I wiped myself I saw blood, so I inserted a new ring, however this period was so light I didnt even need a tampon. Blood was just hanging around up there but never really flowed. This has never happened to me. Help! Im 35.
