Delayed menstruation and breast pain, if it occurs in women of childbearing age who are sexually active, this condition needs to be checked to see if there is a possibility of pregnancy. Menstruation is related to mood, diet, environmental stress, and psychological tension. If there is a problem in any of these areas, it can cause menstrual disorders. Of course, a delay in menstruation of about a week is within the normal range. If menstruation is delayed for more than a week and there has been sexual activity, a pregnancy test should be used to see if there is a possibility of pregnancy. If not pregnant and menstruation is delayed for more than a week, it is necessary to promptly go to the hospital for a gynecological ultrasound to check the condition of the endometrium, and if necessary, medication can be used to induce menstruation. If a pregnancy test is positive, then it is timely to go to the hospital for a pregnancy checkup.
