There are no obvious symptoms of egg fertilization. Egg fertilization refers to the formation of a fertilized egg. Under normal circumstances, after semen is ejaculated into the vagina, the sperm will leave the semen and enter the lumen of the fallopian tubes, and if it happens to be in the period of ovulation and there is an egg being discharged, the sperm and the egg will meet and form a fertilized egg, and there are no too obvious clinical symptoms for women in this process. After the fertilized egg is formed, it will be implanted into the uterine lining within 6~7 days. During the process of implantation, it will invade the uterine lining, and a small number of women may have mild abdominal pain and a small amount of bleeding, but most women do not have any obvious symptoms. If a woman has plans to have children, it is recommended that she arrange to have intercourse at the time of ovulation so that the probability of pregnancy is higher, and she should relax and not be too concerned about how her body feels. If a woman experiences uncomfortable symptoms during her preparation for pregnancy, she should consult a doctor in time and standardize her treatment.
