Breast tenderness is a painful symptom of both pregnancy and PMS. While some women do not experience painful breasts, many find that the tenderness that occurs during pregnancy is much worse than in PMS. Breast tenderness is primarily caused by hormonal changes that take place in the body, and during pregnancy there are heightened levels in hormones.
The breast tenderness that is experienced during pregnancy and PMS are very similar. The tenderness resulting from pregnancy is usually more intense than the tenderness resulting from PMS, and it is combined with visible changes to the breast. Typically, if breast tenderness does not go away after two weeks, it is likely the result of pregnancy or a serious condition.
