Please help...I have been on the nuvaring for 2 years. My last period was the week of march 5th. I typically have mild breast soreness around the start of my period. However, my breasts are very sore at this point-two weeks later. I am very worried-feels like a pregnancy symptom. I have read that side effects can include breast tenderness-but after two years it just starts happening? Has anyone else had this problem?
