Chest pain can occur due to changes in hormone levels in the body, and is usually present before menstruation or during ovulation. If the pain occurs during ovulation, it may take a longer period of time, about fifteen days, before menstruation, which is considered a normal phenomenon. If there is chest pain a week or so before menstruation, it is due to the luteal secretion period caused by the hormone of progesterone, stimulation of the blood vessels of the breasts and the breast pain, usually after a week will come to menstruation. The fact that you haven’t had your period after a few days of breast pain means that the lining hasn’t fully reached a normal menstrual lining, so it’s advisable to observe for a few more days and make sure you have a good routine and don’t eat spicy and stimulating foods, including cold foods, so as not to stimulate your menstrual cycle. If there is a delay in menstruation, you should go to the gynecology department of the hospital as far as possible, and have an ultrasound examination to rule out whether there is any abnormality in the lining.
