I just came on here looking for answers as I am having the same thing!

I have had a Mirena IUD for 2 years now (DS is now 2 1/2). I have had sore boobs for about 5 days, headaches, slightly nauseas today, and really really tired.

I thought - no way could I be pregnant (we already have 3 kids!!) and this was the reason for having the Mirena in the first place. I have no idea when my last period was as it is on and off since I had the Mirena in, but the last time I remember it was only light spotting.

I am looking forward to seeing what your dr says!!
