Sore Breasts - Ouch!
I had been on birth control pills for 15 years and went off to get the Mirena IUD. I have had the IUD since February and right before my period, which is only 3 days and very, very light, my breasts get SO sore and my nipples are PAINFULLY tender. It lasts about 3 days. My breasts always got sore before while I was on the pill, but not this bad. What is causing this and what can I do? The IUD contains no estrogen, could that be it?
