An interesting thing about the 5th week of pregnancy is a fact that a woman can be still unaware of her condition. She can blame fatigue or weather of some unpleasant symptoms, while her body and the fetus undergo enormous changes to ensure the normal course of pregnancy.

What happens at the 5th week of pregnancy?

What can ultrasound show at this time?

  • Ultrasound examination will show the presence of the gestational sac in the uterus.
  • Thus, ultrasound will clearly confirm the fact of pregnancy.
  • Abnormalities in the fetus cannot be detected yet. It is too early.

The buds of the internal systems continue to form in the fetus. At the embryonic stage of pregnancy, the respiratory system is being put in place, and the nervous system starts to develop. At this time, it consists of a single neural tube which ends with a brain germ.

Fetal cells are actively dividing. At this time, a system of blood vessels and a heart is formed. In the future they will begin to function. A woman cannot feel it, but a child’s heart begins to beat. The embryo is 2 mm long.

Despite the fact that very little time has passed from conception, the future child has already formed:

  • a respiratory system;
  • a nervous system;
  • a cardiovascular system.

The fifth week is dangerous because of increased risk of miscarriage. Therefore, a woman should avoid recreational activities and serious physical exertion.

The embryo at the fifth obstetric week is two millimeters long.

Many women worry about their pregnancy. They are especially frightened by the initial stage. In this case, expecting mothers should be informed about all changes occurring in their bodies. Be sure to take into account the peculiarities of the fetal development depending on the duration of pregnancy. This helps women to adjust their lifestyles properly and ensures a safe delivery in future.

The 5th obstetric week of pregnancy is only the 3rd week from the moment of fertilization. It is more correct to consider certain features of the obstetric period of pregnancy and the period that is counted from the moment of conception.

Symptoms and feelings at the 5th week of pregnancy

During this period, the woman becomes aware that she is pregnant. After all, there are all the characteristic symptoms that eliminate any error. The main sign of pregnancy is always the absence of the menstrual cycle.

Despite the early term, the breast begins to get ready for feeding the baby, so it becomes especially sensitive and tender.

A woman should be prepared for probability of early toxicosis during this week.

At the fifth obstetric week, the absence of menstruation tells about pregnancy most accurately.

A woman can feel nauseous not only in the morning, but throughout the day. If the future mother vomits, then such a condition can be called the first trimester toxicosis.

In addition, other symptoms may occur during the 5th week of pregnancy:

  • Constant fatigue and drowsiness. The reason is that the female body spends a lot of energy on the development of the fetus.
  • Frequent urination. Women consume more fluids. It’s not dangerous; some hormones can cause engorgement of vessels and more active kidney function.
  • Abdominal cramps. Such sensations may arise from the implantation of the embryo into the walls of the uterus, as well as due to its stretching. If the spasms are not severe, then the woman should not worry.
  • Minor vaginal bleeding. If a woman noticed small traces of blood on her underwear, then this may indicate embryo implantation.
  • Bloating and constipation. This is caused by a slower movement of food through the intestines. The body extracts from the products the maximum amount of valuable substances that are needed for the fetus. The attitude of a woman to different dishes may change. She may be repulsed by some product she used to eat with pleasure. And vice versa, she may feel an overwhelming desire to eat something unusual.

Week 5 is characterized by constant mood swings, which occur without any reason. A storm of emotions occurs because of the realization that a tiny human is developing in her body. Hormones add to this condition. They can also lead to headaches and fainting caused by dilation of blood vessels.

Now the expecting mother may experience unreasonable mood swings.

However, these signs are not observed in all women, most often the pregnancy proceeds without any particular symptoms.

What is happening to the fetus?

At this time, the woman makes sure that she is pregnant, since all the symptoms and sensations are very characteristic. In some cases, it is difficult to confirm it even with a test. The most reliable confirmation of pregnancy is the blood analysis for the hCG hormone.

By the 5th week of pregnancy, the gestational sac has attached to the wall of the uterus, and the fetus is actively developing. Its weight is less than a gram, and its length is 1-3 mm. Despite its microscopic size, the embryo grows and takes the shape of the letter C. The embryo is a cylinder, the upper part of which is the head and the lower part is the legs.

There is a groove along the trunk, which becomes the neural tube. It transforms into the spinal cord and the entire nervous system. At the end of the tube there is a bulge which will develop into the brain later. Future muscles will be located along it.

The other organs are laid actively. The embryo forms the cardiovascular system. Initially, vessels are formed, and then the heart. The main organ is first presented in the form of a tube, and over time it becomes four-chamber. At this time a special event occurs – on the 21th-22th day from the conception the heart of the fetus begins to beat. In the future, its beating doesn’t stop for a moment.

Paired organs (lungs, kidneys) develop on both sides of the spinal chord. The liver, pancreas and thyroid gland are formed.

Despite the tiny size of the fetus, the rudiments of the arms appear, now similar to the fins. In the area of the head the places are formed where the eyes and ears will appear.

The embryo isolates itself from the chorion, the yolk sac and the amniotic vesicle.

The 5th week of pregnancy from conception is characterized by the active formation of internal organs and systems; therefore the fetus is most vulnerable to negative environmental influences. If the expectant mother takes medications that are contraindicated during pregnancy, or is exposed to chemicals, stress, infection, then this can adversely affect the development of the fetus.

Changes in the female body

The first thing the future woman feels is a decrease in immunity. This happens due to the fact that the embryo has different genetic material than her. Therefore, the amount of hCG in the body increases to prevent rejecting the fetus. The body temperature at week 5 rises to 37.5 degrees, which causes increased fatigue.

There are no special changes in the body of a pregnant woman, and so far it’s impossible to recognize her condition by her appearance. But inside her body, there are violent changes due to an active increase in the level of certain hormones.

Estrogen plays one of the most important roles. Under its influence, the mammary glands are enlarging; the milky ducts are developing and preparing for lactation. The chest swells and becomes more sensitive. Estrogen also affects the general condition of the future mother, she experiences headaches and dizziness. It is believed that this hormone makes her especially feminine.

Estrogen helps to increase the size of the uterus and prepares the body for the upcoming delivery.

Progesterone is a hormone that preserves pregnancy. Its main source is the corpus luteum. It has a soothing effect on the smooth muscles of the uterus and prevents overstrain that can lead to miscarriage. The gastrointestinal tract organs experience the relaxing effect of progesterone, and intestinal peristalsis is slowed down. All this can lead to heartburn and constipation.

Some women in the 5th week of pregnancy may experience symptoms of early toxicosis. The main symptom of this condition is nausea. It usually occurs in the morning. If toxicosis is severe, a woman should consult a gynecologist.

Tugging sensations in the lower abdomen

Symptoms of pregnancy at week 5 include tugging sensations in the lower abdomen. This condition occurs because the female body is used to the fact that the menstrual cycle begins at this time. Dragging pain on the sides of the abdomen can occur due to the growing uterus and the stretching of the muscles and ligaments supporting it. If the pain is dragging, dull and localized in the lower abdomen, this may mean hypertension of the uterus and the threatened miscarriage. If there is also a bloody vaginal discharge, the woman should be urgently sent to a hospital. In this case, the probability of losing a child is high.

If dragging pain occurs, you should discuss it with your doctor. It may have appeared due to intestinal dysfunction. Sometimes pain occurs after long sitting or squeezing the abdomen. And if the pain is associated with the work of the digestive system, then the woman needs to reconsider her diet and take antispasmodic drugs under doctor’s supervision.

What happens to the uterus and belly?

At the 5th weeks of gestation, a woman’s abdomen looks as usual, because it hasn’t grown in size yet. The uterus gradually grows; the expecting mother feels it as jeans or trousers don’t fit in the waist. This is not always caused by an increase in the size of the uterus, but most likely bloat.

A woman begins to gain weight. An increase in body weight is an individual process, which largely depends on the future mother’s physique, metabolism and physiology. On average, the weight of a pregnant woman in the first trimester increases by 450-2,500 g. This is considered a normal rate. Despite the absence of significant external changes, an active hormonal adjustment takes place in the woman’s body. This affects, among other things, the growth of the uterus.

Discharge at the fifth week

There is no menstruation at this stage of pregnancy. If any bloody vaginal discharge appears, a woman should immediately seek medical attention. It signals a danger and a possible threat of spontaneous abortion. And the bleeding may indicate a miscarriage, so going to a medical institution is a must.

Discharge at week 5 can become abundant and watery, but it should not have any odor and color. If it is greenish or yellowish, cottage cheese-like and has unpleasant smell, this is due to the infection that is dangerous for the embryo. Only the doctor can determine the cause of the discharge, so the expectant mother should not self-medicate.

In case of an ectopic pregnancy in a woman, when the egg is located outside the uterus, painful sensations of a cramping nature and bloody discharge can also occur. In this case, you must contact your gynecologist. This is the only way to rule out an ectopic pregnancy. Spontaneous abortion is extremely dangerous for a woman’s health; therefore, she should immediately go to the hospital, if all of the above symptoms occur.

Twin pregnancy

This week, twin pregnancy does not cause any inconvenience for the expectant mother. However, all the symptoms that are listed above may occur in women before this period or be more pronounced. If two embryos are found on the ultrasound scan in the uterus, a woman should take her own health even more seriously. After all, two babies require more nutrients, and the total load on the mother’s body is also doubled.

Photo of the fetus and ultrasound

The 5th week of pregnancy is not the time for routine ultrasound examination. It is usually carried out when a woman becomes registered in the woman’s health clinic. However, if she found out about her pregnancy, an ultrasound scan can be performed to confirm the exact date of conception.

An examination can determine how many embryos are developing in the womb and where they are fixed. Meanwhile, it allows to evaluate the condition of the uterus. Neither the sex nor the weight of the embryo can be accurately determined because of its small size. But you can see the unborn child as a small point, and by the end of the week, with the help of the ultrasound machine, you can hear the small heart beating. If desired, a specialist can take the photo.

Does the test show pregnancy at week 5?

A pregnancy test could show a positive result as early as the previous week. Despite the high accuracy of this device for home examination, sometimes it doesn’t show two bars even after conception. If the expecting mother feels the characteristic signs of pregnancy and has no menstruation, then it is best to conduct the test after some time.

What is early toxicosis?

The fifth week of pregnancy can be characterized by the onset of early toxicosis. The future mothers, who expect twins, face this problem more often than others. Gynecologists associate early toxicosis with changes in the hormonal profile and the activity of the nervous system.

It mainly manifests as nausea, vomiting, increased salivation, weakness, and drowsiness. Toxicosis may be accompanied by increased irritability, depression and weight loss.

In some cases, it proceeds in other forms:

1. Dermatosis of pregnancy. It affects the skin that may be itchy in the genital area or throughout the body.

2. Tetania gravidarum is manifested as the cramps in the muscles of the limbs and face. This happens when the parathyroid glands malfunction.

3. Osteomalacia. It is caused by calcium and phosphorus deficiency in the body. It is manifested by pain in the limbs and increased fatigue.

4. Acute yellow atrophy of the liver. It occurs very rarely. The disease is characterized by a decrease in liver size, jaundice and severe damage to the nervous system. The condition of the woman worsens within 2-3 days and can be fatal. The only way out is abortion.

There are 3 degrees of vomiting of pregnant women:

  • 1st degree (mild). Vomiting can occur up to 5 times a day. This happens after eating or when a woman smells something unpleasant. Loss of body weight is no more than 2-3 kg. The condition of the woman is satisfactory. All test results are normal.
  • 2st degree (moderate). Vomiting appears 6-10 times a day. For 1 week, the expectant mother can lose 3 kg. There is a decrease in blood pressure. A woman has weakness, dizziness and constant fatigue. Urine analysis shows acetone.
  • 3st degree (severe). This condition in women is very rare. Vomiting can occur 25 times a day. A woman cannot sleep because of it. Weight loss is 8-10 kg. The body is dehydrated, the skin becomes dry, and the body temperature rises. Blood pressure is reduced. Urine analysis shows the presence of acetone and protein.

If a woman has symptoms of toxicosis, then she needs to visit a doctor.

When vomiting occurs several times a day, the expecting mother will be advised and allowed to go home. With degree 2 and 3, she will need hospital treatment.

A woman may be prescribed the following procedures:

  • infusion to compensate for the loss of fluid in the body;
  • antihistamines;
  • vitamins of group B and C;
  • drugs that protect against liver cell damage (hepatoprotectors);
  • drugs to normalize metabolism, electrolyte balance and the nervous system function.

Therapy is carried out under the supervision of a physician. If the condition of the woman worsens despite the treatment, abortion is necessary.

Sex at the 5th week of pregnancy

Having sex during this period is not prohibited if the woman has no vaginal bleeding, pain or cramps. If intimacy makes her uncomfortable and there is a prohibition by the gynecologist, then you should avoid it.

Some pregnant women at this time completely lose sexual desire due to increased fatigue and weakness.

Required tests and analyzes

The first study which a woman passes is a pregnancy test. With its help, the level of hCG in the urine is determined. In the early stages its quantity can be extremely low. In controversial cases, hCG levels are determined in the blood. Its increased rate makes it possible to confirm a pregnancy.

Ultrasound scan is performed quite often during this week. This method of diagnosis helps to accurately confirm or rule out the pregnancy. Ultrasound shows the amount of embryos and the size of the uterus. Occasionally, the examination may determine the fetal heartbeat. Ultrasound determines the compliance of the unborn child and the uterus to the expected duration of pregnancy.

Recommendations for the expecting mothers

A pregnant woman needs fresh air. She needs daily walks of at least one hour. It is best to walk away from busy avenues – in parks, forest parks or in the garden. Walking strengthens muscles, accelerates blood circulation and brings great benefits to the expectant mother and child.

During pregnancy, you need to take a special vitamin and mineral complex. It will ensure the normal state of health of the pregnant woman and the development of the baby. If the mother has a calcium deficiency, then the fetus will take this microelement from her bones and teeth. To avoid this, the woman should take the prenatal vitamin complex.

To maintain the required level of iron in the blood, you should use drugs that include this trace element.

It is the best for the woman to start taking vitamins before conception to create ideal conditions for the development of the child.

The future mom needs to change her menu. She has to include more products that contain proteins, carbohydrates and vegetable fats. The woman shouldn’t eat chocolate, honey and citrus fruits, so that the baby has a normal immune system.

The expectant mothers should control their weight. Over the entire period, body weight should not increase by more than 8-12 kg. If the weight grows rapidly, the blood circulation process becomes difficult, which can cause serious consequences for the health and development of the child.

The future mother has to perform a complex of breathing and strengthening exercises. They help strengthen the muscles of:

  • peritoneum;
  • hips;
  • crotch.

During the entire pregnancy, the woman should be monitored by a gynecologist. Ultrasound scan should be done at least 3 times. At any gestational age, this method of examination will determine what happens to the baby and mother with high accuracy. A woman should be tested regularly to control the level of hemoglobin, sugar and other indicators, and to check the body for hidden infections that may adversely affect the development of the fetus.

The pregnant women should avoid stress.

Diet of the expecting mother

A pregnant woman should eat a healthy and balanced food. Her diet must include various dishes from vegetables and fruits, a lot of greens, dairy products, nuts and pulses. If a woman is disgusted by meat, she should eat more vegetable proteins. The expectant mother should avoid smoked and spicy dishes. Instead of frying, the food should be steamed or stewed. Don’t eat too hot or cold food.

Alcohol and coffee are prohibited during this period.

The 5th week of pregnancy is an important time for the future mother and her baby. During this period, the woman becomes aware of the seriousness of her position, and also important organs and systems are formed in the fetus. Proper behavior and care for her health will allow her to give birth to a healthy child.
