Will the embryo implantation cause stomach pain?

In fact, human formation is a relatively complicated process. At the beginning, humans exist in the world as fertilized eggs. The fertilized egg will gradually implant into the woman's uterus, and after implantation into the uterus, the fertilized egg will gradually develop. However, during the process of fertilized egg implantation, various abnormal reactions may occur in the female body. So will embryo implantation cause abdominal pain?

1. Lower abdominal pain may occur when the fertilized egg implants, which is related to embryo implantation and hormonal changes. The sperm and egg combine to form a fertilized egg, which enters the endometrium and completes implantation in about 6-8 days. During the implantation process, the mother will experience some physical changes or discomfort symptoms, but due to individual differences, the symptoms vary from person to person.

2. Symptoms that may occur in the early stages of implantation include: slight pain in the lower abdomen, soreness and discomfort, sometimes accompanied by nipple pain, physical fatigue and other symptoms. Pay attention to rest, improve nutrition, and have regular prenatal check-ups.

3. The process from fertilization to implantation of the fertilized egg is almost silent. Except for a few pregnant women who have physiological implantation bleeding and slight cramps, there is generally no other discomfort. Therefore, if you experience severe lower abdominal pain, you should consider that this may be threatened abortion, ectopic pregnancy, etc., and you should go to the hospital for treatment in time.

What are the symptoms of embryo implantation?

1. Cooling

The fertilized egg moves slowly in the fallopian tube (3 to 5 days), and after several consecutive divisions, it forms a morula and enters the uterine cavity, continuing to develop into a blastocyst (called a blastocyst). The blastocyst is surrounded by the zona pellucida and continues to develop by absorbing the uterine milk secreted by the uterine glands.

2. Feeling tired

Are you always full of energy, but suddenly feel exhausted? The excessive secretion of progesterone (a hormone) can make you feel exhausted. Almost all pregnant women suffer from this symptom, and you can observe other symptoms to confirm your suspicion.

3. Frequent toileting

Have you become a frequent visitor to the toilet? Do you get up in the middle of the night to go to the toilet? If you want to blame someone, blame the little life in your belly! After the fertilized egg implants in the uterine wall, it begins to secrete human chorionic gonadotropin (hcg). If you're tired of getting up in the middle of the night to go to the bathroom, don't worry. Just think of this as training, because in the future, before you know it, your little one will be crying in the middle of the night and saying he's hungry.

After the embryo implants, you should pay attention to taking good care of your body, strengthen your nutritional needs, go to the hospital for regular check-ups, and understand the development of the embryo. The above is the introduction about "How many days will the stomach hurt after the embryo implants?" Women must pay attention to taking good care of their bodies and do a good job of body care.

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

The fertilized egg implants on the 6th-7th day, which means it has reached the uterus. But it is still very small at that time and cannot be seen with B-ultrasound. The small gestational sac can only be seen with B-ultrasound about 20-30 days after implantation.

However, 3-4 days after the fertilized egg implants (that is, after the tenth day after ovulation), a weak positive result can be detected using an early pregnancy test.

Implantation of the fertilized egg is a process of change in the fertilized egg, which means that the fertilized egg is attached to the wall of the uterus.

The fertilization process takes about 24 hours. The fertilization process begins when a capacitated sperm enters the zona pellucida of a secondary oocyte.

When the chromosomes of the egg pronucleus and sperm pronucleus fuse together, it marks the completion of the fertilization process. The fertilized egg divides into 2 cells after 36 hours in the fallopian tube, and divides into 16 cells after 72 hours, which is called a morula. On the fourth day after fertilization, the cell mass enters the uterine cavity and continues to develop in the uterine cavity. At this time, the cells have divided into 48 cells and become blastocysts ready for implantation. The blastocyst can secrete a hormone that helps the blastocyst embed itself into the endometrium. On the 6th to 7th day after fertilization, the blastocyst begins to implant. The implantation site is mostly in the upper 1/3 of the uterus. Complete implantation means that the embryo has been placed, the placenta has begun to form, and the fetus has begun to be nurtured.
