I have had the worst case of severe tension headaches, I would classify them as migraines due to the sensitivity to light and feeling of such disorientation and nausea, followed by loss of appetite. So when I finally eat my stomach goes into shock and I have severe "stomach issues" to put it lightly.No matter what I do I cant shake this feeling of fatigued headaches and Nausea. I am tired of feeling like I am on this emotional rollercoaster. I always feel like I am drugged up and its an awful feeling. The ring is out and I will never go back to using it! I realize each person reacts differently to certain birth controls but I did my research prior to starting the NuvaRing and 8 out of 10 testimonials that I read said Severe headaches, nausea,stomach and bowel problems followed by depression. I would not recommend this to any of my girlfriends. Good luck I hope I can help some woman out there from my experience.
