What to do if you miss a day of birth control pills

The main ingredients of contraceptives are estrogen and progesterone. They are generally divided into emergency contraceptives and ordinary contraceptives. They usually inhibit the secretion of hypothalamic gonadotropin through negative feedback, preventing the maturation and discharge of eggs, and preventing them from combining with sperm to form a fertilized egg. Emergency contraceptives can generally be taken within 72 hours after intercourse to achieve a contraceptive effect. They usually need to be taken on an empty stomach. If you take short-acting contraceptives, you usually need to start taking them on the first day of menstruation. Generally, you need to take them continuously for 21 days to achieve a contraceptive effect. However, if you take contraceptives for a long time, it may cause changes in estrogen in the body, which will affect women's ovulation, and may also affect menstruation and cause menstrual disorders. In severe cases, it will affect fertility. It usually needs to be taken as prescribed by a doctor. You can also wear condoms during intercourse to effectively reduce the chance of pregnancy, or you can avoid pregnancy by implanting an IUD.

Contraceptive pills generally include mifepristone, etc. In addition to their contraceptive effects, they can also be used as abortion drugs. If there is no plan to conceive, it is also necessary to have sex during the safe period to effectively reduce the chance of pregnancy. When having sex, you should pay attention to moderate force and avoid excessive force, otherwise it may cause the condom to break and may also cause genital inflammation and infection.
