Can pregnancy occur if having sex five days before menstruation?

Under normal circumstances, five days before menstruation, the ovarian follicles shrink and cannot effectively combine with sperm, so pregnancy is generally unlikely to occur. However, menstruation in many women is not entirely regular, and the timing of ovulation and the safe period is not particularly accurate, so the possibility of pregnancy still exists. Couples who do not have plans to conceive are advised to take proper contraceptive measures during sexual intercourse. In fact, every sexual encounter carries a certain risk of pregnancy, but the likelihood of pregnancy is affected by the state of the ovarian follicles in the female body.

If pregnancy is not desired, contraceptive measures must be taken. Generally, withdrawing before ejaculation or using a condom are relatively safe options. If there is a longer period of time where pregnancy is not considered, surgical sterilization can also be performed, which has relatively minimal impact on women. Conception is a complex physiological process that involves several key steps. Firstly, the ovaries must be able to release normal eggs, and the semen must be normal and contain viable sperm. Secondly, the egg and sperm must be able to meet and combine in the fallopian tube to form a fertilized egg. Thirdly, the fertilized egg must be successfully transported into the uterine cavity. Finally, the endometrium must be fully prepared to allow the fertilized egg to implant. Any issues in these processes can affect the likelihood of successful conception.

The ovulation period is closely related to menstruation in women. Menstruation is a lifelong intimate friend for women, and ovulation is influenced by the endocrine hormones of the hypothalamus and ovaries, exhibiting periodic changes. The cycles of both are consistent, occurring once a month, and ovulation occurs in the middle of the menstrual cycle. Although women's menstrual cycles may vary in length, the interval between ovulation and the start of the next menstrual cycle is relatively fixed, typically around 14 days.
