"i was 45 when i had the mirena coil inserted. i&#039;d never had children so it was painful but bearable. everyone is different so just make sure you talk any concerns through with your gp. i had a very light period for first three months and occasional cramping but no worse than before i had the mirena inserted, after that i&#039;ve had 4 and a half years period/cramp free. no side effects whatsoever. my 5 years are up so i&#039;m due to have it removed. have been told i&#039;ll experience the same level of discomfort in the removal so at least i know what to expect and it literally does only take a few minutes."
