Eusebio is taken from the first day of menstruation. It is a contraceptive pill that contains estrogen and progestin and is taken for 21 days, preferably at a fixed time every night. This is because this drug contains estrogen and progestin, some women may have nausea, vomiting, dizziness and other symptoms after taking it, and taking it at night before going to bed can reduce such symptoms. You must not forget to take the pill. If you forget to take it that night, you must make up for it within 12 hours, otherwise it will affect the contraceptive effect of the pill. When taking the pill, also note that if it is the first time you take the pill, you must not have sex until 7 days after taking it.
