Hi, I just joined this site in order to ask about this medication. I have a number of health issues, such as Crohn's disease and Rheumatoid arthritis and I have chronic migraines. I've been prescribed the Norethindrone for excessive cycle bleeding. I'm aware that when I begin, it will take at least 3 months to see a change in the bleeding, but I'm reading the side effects and the comments on this board and I don't see anyone who HASN"T experienced some or a lot of bad negative side effects! Anyone out there who also has migraines before taking this medication and didn't see them worsen? Am wary of starting something that will make working and everyday living even harder than it already is... thanks so much..
