What is the embryo implantation process?

Every normal woman needs to go through the process of pregnancy. Pregnancy is a very happy thing for most women, which means that women are about to become mothers. When men ejaculate in women's vagina, most sperm will die, and only a small number of them can successfully reach the uterine cavity and finally combine with the egg, thus leading to female pregnancy. So what is the embryo implantation process?

First, what is the process of embryo implantation? Day 1 of pregnancy: semen is ejaculated into the posterior fornix of the vagina. Most sperm die in the acidic environment of the vagina. Only a small number of sperm pass through the cervix and reach the uterine cavity within 1 hour. After another 1 to 2 hours, the sperm has traveled a total of 18 cm and finally reaches the ampulla of the fallopian tube and combines with the egg to form a fertilized egg. A new life begins here, and in the next 266 days, the baby will develop in your uterus.

Second, day 2 of pregnancy: The first cell division will occur today, and your baby will develop safely. Day 3 of pregnancy: The fertilized egg undergoes 3 to 4 divisions. At this time, cell division and growth depend on the nutrition within the egg. Day 4 of pregnancy: As the fertilized egg divides, it gradually moves toward the uterus due to the movement of the cilia and muscles of the fallopian tube. It reaches the uterine cavity 4 to 5 days after fertilization, and then stays in the cavity for 3 to 4 days.

What is the embryo implantation process? Day 5 of pregnancy: Today the fertilized egg undergoes important changes and is preparing to be implanted in the uterus. Day 6-7 of pregnancy: The fertilized egg adheres to your uterine mucosa and prepares to implant. Day 8 of pregnancy: The implantation process begins. The embryo burrows into the uterine lining, so you may experience some light bleeding. Day 9 of pregnancy: The fertilized egg implantation process is completed today. The embryo is growing very quickly, but it is too early to confirm with a pregnancy test. Day 10 of pregnancy: The first part of your developing baby's body to function is his cardiovascular system. Your baby's heart starts beating a week before your period is delayed. Day 11 of pregnancy: The placenta begins to form where the fertilized egg implants, and blood from your circulatory system begins to circulate in the placenta.
