One of the side effects of the IUD is back pain, but I'm not sure if this counts. It is under my ribs/at the bottom on the right side, and just feels like an aching that lasts hours.
Worried in case an infection could have spread when the iud was put in, and can't seem to find much related to my question except abominable pain. The IUD I had was the Mirena, got it on the 3rd November and all is well at the moment, only had spotting for 2 days after insertion and cramps for a few days.
That happened to me for awhile on and off when I first got my IUD inserted. I've had it two years and it still happens occasionally when I get my "period" (i.e. light spotting) about every three months. My doctor told me that it's normal. Your body is still adjusting to having a foreign object in it, there's nothing to worry about but if it gets extremely painful for an extended period of time then you should call your doctor in case it's something more serious.
