Chest pain can occur due to changes in hormone levels in the body and is usually present before menstruation or during ovulation. If breast pain occurs during ovulation, it may take longer than 15 days before the onset of menstruation, which is considered a normal phenomenon. If breast pain is present a week or so before menstruation, it is caused by the progesterone rush during the luteal phase, which stimulates the blood vessels in the breasts and causes breast pain, usually a week before menstruation. It is recommended to observe the situation for a few more days, to ensure good rest and rest habits, and not to eat spicy and stimulating food, including cold food, so that the stimulation of food will not cause menstruation. If your period is delayed, you should go to the gynecology department for an ultrasound examination to rule out any abnormalities in your lining.
