If you have intercourse during a woman’s safe period and ejaculate outside the body, the probability of pregnancy is very small, about 5%. In some cases, the possibility of pregnancy cannot be ruled out. For example, in some women, although it is a safe period, if there is an unexpected ovulation, during intercourse, although it is an external ejaculation, a small amount of semen is already spilled in the vagina before the ejaculation is about to pull out. This situation can easily lead to pregnancy, but the probability of this is very small, so the probability of pregnancy is also very small. Because women can ovulate unexpectedly under certain circumstances, it is advisable to use effective contraception every time you have intercourse, regardless of the circumstances, if you do not intend to have children, to avoid an unwanted pregnancy. If you are not planning to have children for the time being and have not had any children, it is advisable to use condoms throughout to avoid side effects.
