Is the fetus formed at 55 days of pregnancy? What does the fetus look like at 55 days of pregnancy?

We all know that after a woman becomes pregnant, she will experience different changes at different stages. As the months go by, the symptoms of pregnancy will become more and more obvious, especially the changes in her belly and weight. So how big is the fetus at 55 days of pregnancy? Let's take a closer look!

Is the fetus formed at 55 days of pregnancy?

Pregnant women who are 55 days pregnant are in the early stages of pregnancy. At this time, pregnant women have already experienced pregnancy reactions, but the fetus is still small, only about 20mm long and has not yet formed. In addition, because it is still in the early stages of pregnancy, the fetal placenta is not stable, and the early stages of pregnancy are the period of fetal neural tube development, so pregnant women need to pay more attention to supplement folic acid on time, 0.4 mg per day is enough, and pregnant women need to pay more attention to rest and avoid being too tired.

How big is the fetus at 55 days of pregnancy

The 55th day of pregnancy is what is clinically referred to as the 2nd month of pregnancy, or 7 to 8 weeks of pregnancy. Strictly speaking, this is the stage when the sperm and egg meet, combine, implant and develop into an embryo (4 to 8 weeks of pregnancy). So how big is the "fetus" (embryo) at this time?

Development of the embryo at 7-8 weeks of pregnancy:

1. The embryo is about 13 to 19 mm long and weighs about 0.9 to 1.1 grams. The skeleton and auditory system are initially formed; brain cells develop rapidly, so they are particularly sensitive to information from the mother's body. The head is currently very large, occupying half of the body, and the eyes are also developing.

2. The upper jaw continues to develop, teeth and facial muscles begin to form, the bones gradually harden, and the limbs and head can be supported by hard bones.

3. By the 8th week of pregnancy, the embryo has developed into a human form, the heart, brain, liver, lungs, and kidneys are developing rapidly, the heart beat is returning to normal, and the blood output capacity has greatly improved.

4. The little one starts to "pee", and the external reproductive organs begin to develop, but the shape is not yet visible. At the same time, the umbilical cord has also been formed. The little arms and legs are growing rapidly. The oral cavity is well developed, the deciduous tooth germs begin to grow, and the taste buds also begin to develop.

5. The baby's facial features are complete. But the toes are still connected, like a duck. All the main joints of the fetus, such as the shoulder, elbow, wrist, knee and ankle, have begun to move, allowing it to move its arms and legs. The feet have begun to shed their webbed appearance, and the ankles can be seen.

6. The fetus's tail has disappeared, and it looks more and more like a little adult, delicate and cute, and the development of all parts of the body is on track. And this weekend, the little guy has developed nerve reflexes and likes to move his body in the amniotic fluid.

7. Now all the neuromuscular organs have started to work. The fetal heart has also differentiated into 4 ventricles, and the heart valves have begun to develop. The umbilical hernia has begun to retract, and the fetal small intestine can be seen in the umbilical cord.

Simply put, 55 days of pregnancy (7 to 8 weeks of pregnancy) is a very critical turning point for the embryo (the transition from embryonic development to the initial fetal shape). Various functional organs will undergo initial differentiation to facilitate further development and work after entering the second trimester.

Changes of pregnant mothers at 55 days of pregnancy

The 55th day of pregnancy is 7 weeks and 6 days of pregnancy. From the appearance alone, the pregnant mother's body has not changed much, but the vaginal mucosa of the pregnant mother is congested and darkened, and the uterine wall will become very soft, which can protect the uterus. At this time, the uterus has become as big as a fist, and some pregnant mothers will have a slight bulge in the lower abdomen.

After 7 weeks of pregnancy, some common problems during pregnancy begin to appear, which are what we often call early pregnancy reactions. Most pregnant women begin to experience pregnancy reactions around 6 weeks of pregnancy, which begin to worsen at 7-8 weeks, and gradually ease and disappear after 12 weeks.

1. Frequent urination

The growing size of the uterus puts pressure on the pregnant mother's bladder. At this time, the pregnant mother's frequent urination begins to increase. After the uterus extends beyond the pelvic cavity, the frequent urination phenomenon will be alleviated, and then it will gradually increase as the uterus grows.

2. Nausea and vomiting

At this time, pregnant mothers' morning sickness has become much more severe. Some mothers have severe morning sickness, while some mothers have more severe afternoon sickness, loss of appetite, and just want to vomit.

3. Abdominal pain

Most mothers will experience occasional abdominal cramps at this stage, abdominal pressure without bleeding, and mild cramps are very common. This is because the fetus is developing rapidly.

4. Easy to get tired

At this time, mothers will feel more tired than before. Even if they have done nothing all day, they still feel particularly tired, sleepy, and lack of energy all day long.

What should you pay attention to during the 55th day of pregnancy?

Because at 55 days of pregnancy, pregnant women are still in the early stages of pregnancy, which is a relatively dangerous stage of the entire pregnancy, so pregnant women need to pay attention to the following points:

Prenatal check-up

If the pregnant woman has not been checked before, she can go to the hospital to check the development of the fetus at 55 days of pregnancy to see if the fetus is developing normally and whether the fetal heart and fetal bud have appeared. If the fetal heart is still not visible at this time, you can combine blood test to check hcg or wait a little longer.

Folic acid supplementation

Folic acid is an essential substance for fetal development. After pregnancy, pregnant women need 4 times more folic acid than ordinary people, so pregnant women should supplement folic acid. Folic acid supplementation is beneficial to the development of the fetal neural tube. If pregnant women lack folic acid, it is likely to cause fetal malformations such as cleft lip and palate, spina bifida, and encephalocele.

Get enough sleep

After pregnancy, especially in the early stages of pregnancy, sleep is very important for pregnant women. Because in the early stages of pregnancy, due to the progesterone, the pregnancy reaction of pregnant women will be more severe, which may be affected, resulting in fatigue and sleepiness, or pregnancy reactions such as morning sickness. These pregnancy reactions will affect the normal life of pregnant women, and because the early stage of pregnancy is the main period of fetal development and differentiation, pregnant women must pay special attention to adequate sleep, so as to alleviate the discomfort caused by pregnancy reactions as much as possible.

Reduced activity

Because it is early pregnancy, there is no close contact between the fetal placental villi and the uterine decidua, so the fetal placenta is not very stable. Therefore, pregnant women need to reduce activities in early pregnancy and focus on rest.

Prohibition of sexual activity

Because the fetus is not stable during early pregnancy and the placenta is not stable, sexual intercourse is prohibited during this stage to avoid unexpected situations such as miscarriage.
