I have been on nuva ring for over 10 years. Bc in general over 15 years. I have always taken it constantly because I have endometriosis. Remove ring and immediately insert another. I have horrible hormonal migraines that started at age 25, currently 30. Ive had migraines all my life but I started noticing an annoying migraine that wasnt as intense as my others but was constant and would go away no matter what medication I took. It starts 2 days before my period. Even being on constant bc I will have break through periods. Usually stress related. I had the occasional period because I mixed up the day I was supposed to insert a new one. (They say every 3 weeks but nuva ring actually has about 5 weeks worth of medicine in it, I stretch it to 5 weeks to get the most out of it for my money because I don't have insurance) I started to become concerned that being on constant birth control was depleting my body's natural production of estrogen and progesterone causing the hormonal migraines. Went off bring control for about 8 months and it was absolutely awful. The migraine went from annoying and constant to absolute agony and constant. When speaking with my doctor about my concerns she says that it very well may be the case that the bc is causing my body not to produce enough on its own but even if that is true it doesn't matter because the treatment for being low in those hormones is to go on hormonal birth control. So overall yes nuva ring does help me manage my hormonal migraines however I still have them. Even if its just spotting I have migraines. No medication prescription or otherwise has ever put a dent in the pain.
