The fourth week of the 40 week pregnancy: implantation of fertilized eggs

At this time, the endometrium of the expectant mother is affected by the hormone secreted by the ovary, becomes plump, soft and nutritious, the blood vessels are slightly expanded, and the water is sufficient. The fertilized egg constantly divides cells, and forms a solid cell mass after moving into the uterine cavity, called the mulberry embryo body. At this time, the fertilized egg is called the blastocyst. When the peripheral zona pellucida disappears, the blastocyst contacts the endometrium and is buried in the endometrium, which is called "implantation" Implantation usually starts 6 to 7 days after fertilization and finishes within 11 to 12 days.

Physiological changes of expectant mothers

During this period, most pregnant women have no conscious symptoms, and a few people may have symptoms similar to colds: fatigue, fever, chills, etc. The size and shape of the uterus and breasts can not be seen to have changed. The uterus is about the size of an egg.

Tips: Because there is no conscious symptom of pregnancy, most pregnant women do not know that they are pregnant. They hope that married women of childbearing age should pay attention to their physical conditions. Once they find signs of pregnancy, they should not take drugs at random, do not accept X-ray examination easily, and do not participate in strenuous sports activities.

Healthy diet

The daily intake of folic acid in pregnant women should be about 1 mg. The lack of folic acid in pregnant women will cause embryonic cell division disorders, resulting in abnormal embryonic cell division and embryonic cell development.

Sports health care

In order to prevent or alleviate the appearance of stretch marks, it is best for expectant mothers to take proper exercise from now on to increase the skin's ability to resist pulling.

Fetal development

During this period, the brain has begun to develop - one week after fertilization, the fertilized egg will continue to split, some of which will form a brain, and the rest will form neural tissue. The fertilized egg before 9 weeks of pregnancy is called "embryo" or "embryo", This week, we can see that it looks like a small pine nut through B ultrasound. The week of embryo development is called "embryonic stage". The embryonic cells divide at an amazing speed in a few weeks.

What signals does pregnancy send?

Mothers who want to have children should pay attention. Pregnancy is not without signs. If you carefully observe the small changes made by your own body... All right, you have unveiled a huge "surprise": Wow, pregnant!

amenorrhoea

Healthy women of childbearing age, with regular menstrual cycle, a history of sexual intercourse, no reliable contraceptive measures, no sudden changes in living environment, violent emotional fluctuations, excessive fatigue and other situations, are very likely to become pregnant if their menstruation is out of date for more than 10 days.

Nausea and vomiting

About 40 days after menopause, most pregnant women will have nausea and vomiting, especially when they are fasting in the morning. They will have anorexia, indigestion and other symptoms, ranging from greasy to anorexia, and even suddenly dislike certain smell, or have a special preference for certain foods, such as sour (preserved apricots), spicy food, etc.

Lethargy

Although healthy during pregnancy, she always feels tired, weak, or has no interest in doing things. She is drowsy all day long and can't lift her spirits.

Breast changes

At this time, the breast swells, aches, and gradually increases, the nipple feels tingling, the areola becomes larger, and begins to color (color deepens), and veins can be seen under the breast.

Frequency of urination

First, because the maternal metabolites increase after pregnancy, and the infant metabolites also have to be discharged from the mother, which greatly increases the workload of the kidney and increases the urine output. The second is that the enlarged uterus or the descending fetal head compresses the bladder, reducing the capacity of the bladder and causing an increase in the number of urinations. If it is just excessive urination and frequent urination, it is a normal phenomenon and does not need special treatment. After the baby is born, the symptoms will naturally disappear.

Elevated basal body temperature

Under normal circumstances, after ovulation, the basic temperature curve of a woman will rise by 0.3-0.5 ℃ due to the effect of progesterone, until the first day of menstruation or 1-12 days before menstruation begins to decline. If the basal body temperature rises and menstruation expires in the future, the basal body temperature will continue to fall. If it lasts for 16 days, the possibility of pregnancy is greater. However, other factors that may cause temperature rise, such as systemic infectious diseases, should be excluded.
