You can take Eucerin on the 2nd day of your period. Generally, Eucerin is taken on the first day of your period, and you take one tablet every night and stop taking it for 21 days. If it is the 2nd day of menstruation, the difference of one day is not significant. If it is the patient’s first time to take Eusebio, he or she should not have sex until 7 days after taking it. If you have sex before, you must use condom contraception, otherwise you will easily get pregnant. If the patient wants to take Eusebio for a long time, he or she should stop taking the pill for 7 days after the first box and start taking the second box of Eusebio on the 8th day, regardless of when his or her period comes. You should never stop taking the pill on your own while you are taking it, otherwise it can easily lead to pregnancy.
