I have had mirena for 3 years. I have never had any problems with it. But recently I was feeling aches in my abdomen and my vagina they said I had pid. They gave me antibiotics but Im still feeling weird. My legs have been sore, dull pains on my abdomen, sore breast. and it is time for my period and today i discharged a little brown, then a bright red color just a little, hours after nothing can I be pregnant? This has been going on for three weeks
