Some women may ovulate shortly after menstruation, while others may ovulate just before menstruation. This variation increases the uncertainty of safe-period contraception.

Although safe period contraception has a certain contraceptive effect in theory, there is a great risk of pregnancy in practice. Here are some reasons that may lead to the failure of safe-period contraception:

two。 Sperm survival time: sperm can survive in a woman for as long as several days. This means that even if you have sex during a safe period, it can still lead to pregnancy if the sperm enters the woman's body before ovulation and survives.
3. Extra ovulation: in some cases, women may have extra ovulation during the non-ovulatory period. Although this is not common, once it happens, it will greatly increase the failure rate of safe-period contraception.
