Lower abdominal pain and breast pain are some symptoms that appear before menstruation. Before menstruation, there are significant changes in the levels of estrogen and progesterone in the body. An imbalance in the levels of these hormones can lead to symptoms such as breast pain and lower abdominal pain. These symptoms typically disappear with the onset of menstruation, so it is a normal phenomenon and does not require special treatment. These symptoms could also be early signs of pregnancy, as early pregnancy reactions. In the early stages of pregnancy, the levels of estrogen and progesterone in the body increase significantly, which can cause breast pain, lower abdominal pain, and other early pregnancy reactions such as nausea and vomiting. When experiencing lower abdominal pain and breast pain, one should first consider the menstrual cycle and whether there is a delay in menstruation. If the menstruation is delayed, pregnancy should be considered. If it is just before an expected menstruation, these could be premenstrual symptoms.
