Ovulation day has been normal, indicating that the menstrual cycle is more regular, sexual intercourse during ovulation, the chances of pregnancy will be higher. If the couple wants to get pregnant, they can go without a condom, which is conducive to getting pregnant as soon as possible. If the couple does not want to get pregnant, they should wear a condom the whole time, whether they have intercourse during ovulation or non-ovulation.
Safe period contraception is unreliable, so even if the day of ovulation is regular and you are able to avoid intercourse during ovulation, you should still choose a more effective form of contraception, such as condoms, in order to avoid unwanted pregnancies and unnecessary abortion injuries.
