"i had the mirena put in when i was 30 and no one warned me about the pain, so i just sucked it up and dealt with it. i&#039;ve had mine in for 3yrs now with no problems. the first year i would say did suck with all of the random bleeding. now i rarely cramp and the periods are very light so i can&#039;t really complain. some positions during sex can be uncomfortable so i just adjust."
