I have been taking the neuva ring birth control for over a year now and during this period I had last week I started cramping ready bad and then went to the bathroom and a thick white jelly mass came out and it has really scared me. I have an appointment by my doctor next month. Should I be worried? The thing that came out was very thick and seemed like it could have been a lining of something. Only the outer part was bloody and when it came out my cramping stopped.
