How many days does it take for the fertilized egg to implant?

Generally speaking, in order for the fertilized egg to implant normally, the egg and sperm must be able to combine normally. The sperm and egg can only combine for about 2 days, which means that the egg and sperm must touch each other and combine together in about two days. Only under this circumstance can the fertilized egg implant and then slowly enter the uterus and form an embryo.

Implantation begins around the sixth to eighth day after fertilization and is complete on the eleventh to twelfth day. Generally, implantation occurs slightly more often on the posterior wall of the uterine body than on the anterior wall, and more often in the midline than on the lateral wall. The entire process of the fertilized egg moving in the fallopian tube toward the uterus after combination is carried out quietly, and the mother does not feel anything. Even after the fertilized egg implants, most people do not feel anything, but many people will experience a small amount of bleeding (referred to as implantation bleeding due to changes in hormone levels), and some people will experience mild abdominal pain or back pain. The fertilized egg absorbs nutrients and oxygen from the fluid secreted by the fallopian tube and continues to undergo cell division. After the fertilized egg implants, it gradually develops in the uterine cavity. After 5-8 weeks of menstruation, the fertilized egg develops into an embryo, and after 9 weeks, it develops into a fetus. In other words, pregnancy is only possible if you have normal sexual intercourse during your wife's ovulation period.

Therefore, the implantation of the fertilized egg requires the normal combination of the egg and sperm. Only when the woman ovulates normally will the sperm have the opportunity to combine with the egg. Women should pay special attention to changes in their bodies, and if symptoms appear, they should consult a doctor in time to find out whether the fertilized egg has safely implanted.
