Patient's question:
At the age of 28, a few days ago I took birth control pills, and my period hasn't come yet. Is it possible that taking birth control pills can cause irregular periods?Doctor's answer:
Hello: It is important to consider the adverse reactions of birth control pills. Due to their effects of inhibiting and delaying ovulation, as well as suppressing the uterine lining, birth control pills can cause the next menstrual period to be delayed. Additionally, temporary use may lead to a temporary increase in hormone levels in the blood, followed by a drop and subsequent withdrawal bleeding, which may manifest as an early menstrual period. The side effects may include symptoms similar to early pregnancy, vaginal bleeding, reduced menstrual flow or amenorrhea, endocrine disorders, weight gain, facial hyperpigmentation, infertility, or gastrointestinal discomfort, headaches, weight gain, nervousness, low mood, skin spots and acne, among others. It is recommended that emergency contraception should not exceed three times within a year and can only be used once per month. Wishing you good health!
