There is no such thing as a safe period in medicine, only relative to the ovulation period. Whether or not two days after menstruation is a safe period needs to be judged according to the individual’s menstrual situation.
If your period is relatively regular and lasts for a short period of time, about 3 to 5 days, the two days after your period generally fall into the category of safe period. If menstruation is not regular or lasts longer than 5 days, the two days after menstruation are not necessarily a safe period and ovulation may occur.
Safe period has a certain relationship with the menstrual cycle and the duration of menstruation, and the safe period is not absolutely safe, if you want to contraception can choose to use condoms or take contraceptive pills, relatively speaking, the contraceptive rate is higher.
Normally, you need to observe your body more often, if there is pregnancy or irregular menstruation, you need to actively seek medical attention.
