birth control
"I tried the mirena for 1 year. The inserting was not painful for me at all but the next day I had level 10 pain and was concerned but all was fine. it ended up completely stopping my periods which was the only thing I loved about it. About 6 months into it sex started to hurt really bad with it and i was also starting to have really bad black out spells. I actually ended up seeing a heart specialist because they thought it was something to do with my heart. I told the specialist I think its my mirena.  I would have the mirena checked on a reg basis by my gyn due to pain and such. One day I ended up getting so fed up with it all I told my gyn to take it out. Since then I have had no issues with blacking out even and sex became non painful."
