It’s not absolutely safe to have intercourse when your period is delayed, but you should combine it with the delayed time to make a judgment. If the delay is shorter, it is relatively safe to have intercourse, if the delay is longer, it is less safe to have intercourse at this time. If your period is delayed for a short period of time, you may not get pregnant if you have intercourse at this time. If your period is delayed for a longer period of time, ovulation is more difficult to predict, and it is less safe to have intercourse at this time, which may lead to pregnancy, so it is recommended to take contraceptive measures. At the same time, if menstruation is delayed, it is recommended to check whether you are pregnant or not. If you are already pregnant, intercourse at this time may cause miscarriage and bleeding. If your period is delayed, it may come at any time, so it is not recommended to have intercourse at this time. If you need to have intercourse, it is recommended that you take safety precautions. There is no absolute safe period in the menstrual cycle, and clinically the failure rate of using safe period contraception is high. Therefore, if you do not plan to get pregnant, it is recommended that you take proper contraceptive measures.
