It is possible to get pregnant during the safe period, but the chances of getting pregnant during the safe period are lower than the chances of getting pregnant during ovulation. The safe period refers to the non-ovulatory period and the safe period. If a woman has irregular menstruation, ovulation cannot be determined, so the safe period cannot be determined either. If the safety period is projected simply from the menstrual cycle, it is actually inaccurate, even for women with regular periods, there is still a possibility of unwanted pregnancy. For women with irregular periods, the possibility of pregnancy during the safe period is even greater. Therefore, even if you have intercourse during the safe period, you need to take the necessary contraceptive measures to avoid unwanted pregnancy, which can cause more harm to your body. If no contraceptive measures are taken before intercourse and there is no plan to prepare for pregnancy, women can take some emergency contraceptive pills for prevention. There is still a possibility of pregnancy during the safe period. To avoid unwanted pregnancy, it is recommended to use contraceptive measures such as condoms before having intercourse. Long-term use of birth control pills is generally not recommended due to their potential to cause harm to the body.
