Hi I have been with my partner for awhile now.We had to stop using the pill it was uneffective regards to Bi-polar medication.I now have the IUD.The five year one.I believe it is called mirena.Something like that.Is it possible for me to be pregnant even though I have this placed in me.I have had much pain in my lower back and front.No breast soreness though.How affective is the IUD?What if you are on the medication Tegratol/Will this effect it too.The doctor said that it wouldnt becuase it is placed in the vigina.But I need the facts.Thank you,Hoping For The Best 8-|
