The first few days of ovulation are considered safe. Generally speaking, it is not easy to get pregnant during safe intercourse, but there is still a possibility of pregnancy. Because a woman’s ovulation period is affected by many factors, such as the external environment, climate, her emotions, health status and diet, all of which can affect the time of ovulation. This can lead to early or delayed ovulation, as well as the possibility of additional ovulation, so it is still possible to get pregnant when having intercourse during the safe period. If a woman does not want to have children, it is recommended that she take birth control when having intercourse during the safe period.
