After 8 days of menstruation either 5 days clean or 7 days clean, are in the ovulation phase, so the chances of pregnancy are very high at this time of intercourse. If you are not planning to get pregnant, it is recommended that you use a condom during the entire sexual intercourse to achieve a better contraceptive effect and avoid the possibility of pregnancy. If you are planning to get pregnant, you can choose to have intercourse at this time, and it is also recommended to arrange the time of intercourse during the ovulation period, which will increase the chances of getting pregnant, and to rest in bed for at least one hour before getting up, which will reduce the possibility of getting pregnant due to the large amount of semen outflow. In addition, if you have intercourse after 8 days of menstruation, you should pay attention to sexual hygiene, otherwise it is easy to cause inflammation of the reproductive tract and lead to infection, which is not favorable to the pregnancy.
