I have been on the NR for about two weeks nows. Since I started the ring I have noticed much nauseousness and stomach pain.. I like most other women have been extra tired and have experience a loss in sex drive, and much back pain. My ovaries feel like they were in a fight and lost. I was on pill BC ( alesse) because i used to experience a lot of discharge and he low hormones cleared it up almost completely, after three years on that I started having breakthrough bleeding and my doctor thought I should try the ring because she thought it was so good.. but the increase of discharge has been so heavy i have to wear a liner everyday. The past three days i have also been having mild headaches. I am going to call my doctor tomorrow.. Its good to know its not just in my head.. Good luck to everyone who has had bad luck with the NuvaRing
