i got my mirena inserted in august 2006 wanted get tubes tied but the gyno said the mirena is reversible if anything was to happen to my kids. i was still breastfeeding but trying to stop i didn't think anything of it when my breasts became tender but now that my daughter is completely weaned (i was so tired that she used to feed in the middle of the night when i was asleep) i have noticed a discharge that is similar to the discharge when pregnant i have asked the doctor to remove it but he has told me to give it another 3 months i am going to find another doctor but because i need antibiotics when having it inserted and removed i am going to have two appointments in the one day
