BC side effects??

Rebecca

Ive been using the Nuva ring for a couple years now on and off but just recently ive been noticing with my <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> that "when im ovulating" my breast are VERY SENSITIVE!! Almost painful....

I want to believe that is just the hormones in the ring, but does anyone else experience anything similar?
