Can breast tenderness be related to my Mirena IUD?

Hello, I have, for about 2 years and a half, an important sensitivity in my breasts (pain when moving (ex: going down stairs, jumping, etc.) and sensitivity to touch). When this sensitivity is present, it can last between 1 and 4 consecutive weeks. The sensitivity then goes away and returns a few weeks later. I have not associated this sensitivity with my menstrual cycle (especially given that it can last for a few weeks). Since August 2015, I have had the Mirena IUD. Before that, I had been on the Alesse birth control pill for 10 years. When I talked to my doctor about it at my last annual appointment, she only told me it must be hormonal... I'm wondering if breast tenderness could be a side effect of the IUD; if the hormone released by the IUD could induce breast tenderness in some women. If not, could the natural production of hormones in some women cause this sensitivity? I have no lumps in my breasts or underarms. There is no history of breast problems in my family
