The methods of taking the pill are as follows: 1. Long-term contraceptive pill, which is characterized by a small number of doses and a long contraceptive time, taking one pill on the fifth day of menstruation and another one after 20 days, and so on. 2. Short-acting contraceptive pill, which is taken on the first or fifth day of menstruation and stopped after 21 days, and taken at the same time after the onset of menstruation. 3. Emergency contraceptive pill, which is taken within 72 hours after unprotected sex. The earlier you take the pill, the better the contraceptive effect. The pill can lead to delayed menstruation, dilution, and even amenorrhea, and can also cause breast enlargement, uterine fibroids and other diseases, and should not be taken for a long time.
