Birth control pills delay menstruation for a few days

Contraceptives may delay menstruation for about 7 days, but the specific conditions vary from person to person.

Contraceptives contain hormones, such as progesterone, which affect the balance of hormone levels in women and may interfere with menstrual cycles. When hormones act on the endometrium, they may cause changes in its proliferation or secretion, which may cause menstrual changes. Different women respond differently to contraceptives. Some women may be more sensitive to hormones and delay menstruation after taking them. If

the menstrual delay is longer or accompanied by other abnormal symptoms, such as abdominal pain, abnormal bleeding, etc., you should seek medical attention promptly, conduct relevant examinations, such as ultrasound examination, hormone level detection, etc., to clarify the cause, and take corresponding measures under the guidance of a doctor. At the same time, when using contraceptives, you should strictly follow the doctor's advice and take them correctly to reduce the adverse effects on menstruation.
