Can contraceptives lead to early menstruation?

Contraceptives can lead to premature menstruation.

Many contraceptives contain estrogen and progesterone, which affect a woman's endocrine system. When hormone levels change, they may interfere with the normal menstrual cycle, resulting in premature menstruation. Secondly, when taking contraceptives for a period of time, the sudden change in hormone levels causes the endometrium to lose hormone support and strip bleeding, which may be mistaken for premature menstruation.

If premature menstruation occurs frequently, bleeding is abnormal or accompanied by other discomfort symptoms, such as abdominal pain, dizziness, etc., seek medical advice and conduct relevant examinations to rule out other potential health problems. At the same time, when using contraceptives, you should strictly follow the doctor's instructions. Do not change the dosage and timing at will to reduce the occurrence of adverse reactions.
