Is it normal to delay menstruation by 15 days after taking birth control pills

A 15-day delay in menstruation after taking the pill may be normal, but it may also be abnormal.

Contraceptives contain hormones that may interfere with menstrual cycles. Some women may experience side effects such as delayed menstruation, early menstruation, or changes in menstrual volume. A 15-day delay in menstruation is usually normal. If the period is delayed and accompanied by other discomfort symptoms (such as abdominal pain, vaginal bleeding, etc.), you should seek medical advice.

Adequate sleep, a balanced diet, and appropriate exercise are needed to help regulate endocrine and menstrual cycles. If the period is delayed for a long time and the cause cannot be determined, it is recommended to consult a professional for targeted treatment advice.
