What are the symptoms of 5 weeks pregnancy?

The fifth week of pregnancy is in the early pregnancy period, when the embryonic development is not yet stable and is only the size of a small seahorse. In addition, mothers will also experience some physical changes when they are 5 months pregnant. Especially for some mothers with special physical conditions, they may experience severe morning sickness. In addition, early pregnancy reactions such as breast tenderness, fatigue, frequent urination, irritability, and drowsiness will also slowly appear in pregnant women at this time.

1. Fetal development

At this point, the fetus grows to 0.4cm and looks more like a small seahorse. This week the fetus officially enters the embryonic period. It is now composed of three germ layers - ectoderm, mesoderm and endoderm. These three germ layers will form the baby's organs and tissues in the future. As the embryo develops, the amniotic cavity expands accordingly. During this week, the fetus's primitive cardiovascular system appears and begins to pulsate. At this time, the gestational sac cannot be distinguished by the naked eye, but it can be seen from B-ultrasound that the gestational sac occupies less than 1/4 of the uterine cavity.

Cells are differentiating to form the major organs of the fetus (such as the kidneys and liver), and the neural tube begins to develop. The neural tube is differentiated from the upper layer of the embryo, the ectoderm, and will develop into the baby's brain, spinal cord, nerves, spine, etc. The ectoderm will also form the baby's skin, hair, nails, mammary glands, sweat glands and tooth enamel. The fetal heart and circulatory system begin to differentiate and form from the mesoderm.

In fact, during this week, the baby's little heart has begun to divide into ventricles, started beating, and can pump blood. The mesoderm will also differentiate into the baby's muscles, cartilage, bones, subcutaneous tissue, etc. The third layer, the endoderm, will form the baby's lungs, intestines, early urinary system, as well as the thyroid, liver and pancreas. At the same time, the initial forms of the placenta and umbilical cord, which supply nutrients and oxygen to the fetus, have begun to work.

2. Changes in Mom

The body shape and weight of pregnant mothers will not change much this week. Some pregnant mothers may be slightly heavier than last week, about 0.03kg, but most mothers will not feel the changes in their body shape and weight.

You may experience pregnancy symptoms such as nausea, morning sickness, breast tenderness, fatigue, and frequent urination. At this time, you are moody and anxious; you have a keen sense of smell and hate cigarettes, alcohol and other beverages; you are easily tired and sleepy, and feel general fatigue and exhaustion. If your period is usually regular, but this week your period didn't arrive as expected, then you may be pregnant.

If you experience vaginal bleeding accompanied by mild abdominal pain and back pain, you should go to the hospital for examination.

Early pregnancy reaction: Starting from this month, you may feel nausea, vomiting in the morning, loss of appetite, etc. You can suck on some ginger slices, soak orange peel in water, or take appropriate amounts of vitamin B6, all of which can help relieve morning sickness. These early pregnancy reactions will generally disappear slowly around 12 to 14 weeks. You should relax and not have too much psychological burden.

4. Diet to deal with blood deficiency and anemia: If you suffer from blood deficiency and anemia, you can eat some red dates, wolfberries, red beans, animal blood, liver and other foods; if you are prone to fatigue and colds, you can eat some astragalus, ginseng, American ginseng, etc.; if your spleen and stomach are weak, you can eat some yam, lotus seeds, white lentils, etc. to nourish the spleen and stomach.

5. Sexual life in early pregnancy: After pregnancy, your sexual desire will often decrease, and sex will make you feel uncomfortable. You can communicate with your husband. For the health of the fetus, you should try to reduce sexual life in early pregnancy. You can meet his needs through caressing and hugging.
