I got the IUD in may 2007 after my son was born i loved it, my periods stopped and things couldnt have been better. December 2009 i started getting my periods again, they would last a few days then go away. then around Feb 2010 my periods would go for 3 days then off for 2 then on for 3 then stop for 2. it got to the point i felt i was alwyas on my period. i went to my doc who said it was probably a hormone inbalance and gave me some pills they also have done 2 ultra sounds and to make sure the IUD is in place, because my stings got cut when they did a cancer biopsy. things were fine for a month after the pills then i started having periods again. its now oct i have not had a period in 3 months and i am not sure if i should be worred. i am moody, sore breasts and am gaining weight, the pregnancy tests are comming up neg. and my doctors say not to worry..... has any one else had this problem. i am really getting to the point its not worth it, if i always have to question whats going on..... any one have suggestions?
