I am an 18 yr old who switched from yaz to mirena I got mirena in on 08/14/2015 six days later the cramping is really getting on my nerves as is the brown discharge even though it is slowing down but the cramping is on and off every day sometimes pretty bad to the point I cant get comfortable and my boyfriend is rubbing my tummy to help alleviate the cramping since motrin is not helping ..Just wondering what I am supposed to do or how long this will last my tolerance is almost to its limit ..Help
