"Hello. I thought it was important to wait before sharing my experience until I reached the 4 months mark since the recommended time frame to give your body time to adjust to the device is between 3 to 6 months. After 4 months my side effects have began improving with the amount of bleeding but not the length. See below my chart that I've been keeping track of. I got the device August. I started recording in October. August & September were the worst with extremely heavy bleeding. (My body was adjusting, then the heavy periods disappeared and became regular periods)
October - 5 days of spotting, 2 heavy periods, 1 light period. November - 4 days of spotting, 3 regular period, 1 light period. December - 5 days of spotting, 1 light period."
