"i was put on this medication to help with pain associated with endometriosis. i have suffered with it for years. when i first started it, i had break through bleeding, extremely sore breasts and mood swings. eventually after a couple months, my body adjusted and the breast tenderness subsided pretty much and i no longer had irregular bleeding. i was instructed to take this medicine for 3 months continuously and have a period only once every 3 months. i also suffer with migraines so my doctor put me on topomax 50 mg to help prevent them. the medicines interacted each other and i bled so heavily and had labor like cramps. i stopped topomax and my body still hasn&#039;t regulated."
