My breast have been sore for about a week, heavy, and the nipple has been sore to the touch. I now that this is something that happens close to the cycle, but mine have never been like this before and hurts to lay on them. It has been coming and going. I just had a cycle to end but it wasnt normal. Last month my cycle was late and this month it a day later and was different lighter. I had been experiencing a fever when I get up in the norning that has left when my cycle came. I was having back pain, and pelvic pain during the cycle which was werid. What is it?
