IUD MIRENA, SORE BREASTS?!

Ranisha
So today makes 77 days, no period & negative test! I have an EXPIRED IUD. It's been expired since January 2016. I have had crazy pregnancy symptoms & right now EXTREMELY sore breast & can barely sleep on my stomach!! Anyone else get extremely sore breast without a period?? SN: I don't usually have sore breast on period and definitely not this sore!
