"17 with no children. had the mirena inserted 3 days ago, insertion was agonising, had to take strong tablets to &#039;knock me out&#039; so i could sleep. had the next day off school and i am still on pain relief tablets. went on a short bike ride today and pain returned. can&#039;t wait for the pain to disappear. hopefully the mirena will help me to get on with a normal life."
