HI, I am 21 years olds and my breasts have been constantly tender and swollen for about three months now. Its not intense pain but it is sore to touch. I have had my period each month and its been as normal as its always been. I am sexually active but with only one person. I have not taken a pregnancy test yet because I haven't missed a period and I have not had any other signs of pregnancy. What could be causing my breast to be swollen and tender? Could I be pregnant even if I have no signs or symptoms and get a period every month?
