im 27 and have 2 kids, i had the mirena put in after my 2nd child as ive always had very bad periods.i also have nerve damage in my stomach which gets irritated sometimes by the mirena.i have recently found out as im due 2 have my coil changed that after 5 yrs it could be expired and i might be pregnant. and after 5 yrs of bad moods and stomach pain i could be pregnant thats the only reason i got it in the 1st place was so i didn't get pregnant.ive also had overian cysts which i think are related to my coil as i haven't had a period in 5 yrs but the doc's keep telling me its nothing 2 do wit the mirena.im hoping to get it removed soon still debating on weather or not ill get a new one.
