The early pregnancy reaction in the early stages of pregnancy will increase the physical and mental stress of pregnant friends, and the impact on the growth and development of the fetus in the early stages of pregnancy is quite large. Among them, everyone is very concerned about the implantation of the embryo in this stage. So, will there be abdominal pain when the embryo is implanted in the early stages of pregnancy? There will be pain when the embryo implants in the early stages of pregnancy, but everyone is different. Abdominal pain in the early stages of pregnancy, such as needle-like pain, menstrual-like pain, bloating, etc., are all normal. This kind of abdominal pain is generally not caused by embryo implantation. The fetus grows in the uterus. In order to provide sufficient growth space for the fetus, the uterus also stretches the uterine muscle layer and ligaments as it grows. This can cause pregnant women to feel uncomfortable in the early stages of pregnancy. During a woman's childbearing years, her uterus and ovaries release a perfect egg every month, and the ovulation period is about 14 days before the next menarche. After the egg cell is discharged from the uterus and ovary, it is immediately sucked into the fallopian tubes by the fimbria of both fallopian tubes and waits for the arrival of male sperm in the ampulla of the fallopian tubes. Sperm can survive in the female fallopian tube for 1-3 days, and the egg can survive for about 1 day. If sexual intercourse occurs within a few days before or after ovulation, the sperm and egg may meet in the ampulla of the fallopian tube. At this time, a group of sperm surround the egg, and the heads of the capacitated sperm secrete acrosome enzymes to dissolve the corona radiata and zona pellucida around the egg, paving the way for the sperm to enter the egg. Finally, only one sperm enters the egg, and then a new cell is formed. This cell is called sperm-egg fusion or fertilized egg, and this process is called fertilization. |
