Contraceptives are categorized into short-acting, long-acting, or emergency contraceptives. Commonly, long-acting contraceptives, such as those taken orally once a month, have significant side effects. Prolonged use can lead to menstrual irregularities, facial pigmentation, hyperpigmentation, and amenorrhea. Therefore, long-term use of long-acting contraceptives may result in decreased ovarian function, leading to infertility. Generally, emergency contraceptives and short-acting contraceptives have relatively minor side effects. Occasional use does not have a significant impact, but prolonged use can cause menstrual disorders and hormonal imbalances, which in turn can lead to infertility. Thus, contraceptives are not suitable for everyone, and it is not recommended for women who have never given birth to use oral contraceptives for contraception.
