Here's my situation: I've been using the NuvaRing for approximately 5 years. Haven't had any problems think its great. Prior to the 5 year stint of Nuva Ring, I used it on and off for 2 years, during which time I still got a period sporadically, (sometimes every month, occassionaly every other month) and once not having one for 9 months.
I no longer have a period at all. Haven't had one since 2010. I have subtle symptoms of PMS i.e. tender breasts and sometimes moody. Is there a reason I'm not having a period? Should I be concerned? Is this normal? I eat healthy, exercise 5x/week and am generally healthly.
