Birth control pills taken within 72 hours after intercourse can achieve the effect of contraception, but the earlier they are taken, the better the effect will be. Long-term use of birth control pills is not recommended, as it may have a certain impact on women's menstruation, and in severe cases, it may even lead to amenorrhea. Therefore, those who do not want children should choose a scientific and healthy method of contraception.

Methods of Birth Control

1. As a post-coital contraceptive, emergency contraceptives are usually taken within 72 hours after intercourse, with the first pill taken immediately and the second pill taken 12 hours later. The earlier they are taken, the better the effect. The main ingredient of emergency contraceptives is progesterone, and their mechanism of action is basically the same as that of short-acting contraceptives, suitable for women under 40 years old.

2. Short-acting contraceptives should be taken starting from the 5th day after the onset of menstruation, with one pill taken every night for 22 consecutive days, providing contraception for 1 month. The main function of short-acting contraceptives is to inhibit ovulation and prevent normal endometrial growth, suitable for women without underlying diseases or diabetes.

3. Nausea may occur after taking contraceptives, but it usually does not last more than 24 hours. Therefore, if you experience nausea, do not panic. It is a normal phenomenon and will subside after some rest.
