Let me start with I have been on the birth control pill, mirena and nuva ring I have had problems with all of them. The nuva ring was the last one I had and I had that removed since August maybe before that. I had my period around September 5 I started it back October 9 it is now December 9th and I haven't had another menstral since. My menses have always been irregular but I always had them everymonth. I have taken a pregnancy test on Monday it came up negative. What is wrong with me I haven't been stressed or nervous I just don't know what is going on
