The 5th week of pregnancy – the onset of mood swings and increased urination (SCHOOL OF REPRODUCTION & MOTHERHOOD)

The fifth week of pregnancy is the week of the beginning of severe mood swings in pregnant women. Feeling the need to urinate, chest pain and wet mouth are other symptoms of the fifth week of pregnancy.

Feeling the need to urinate frequently, no matter how small, excessive salivation, or chest pain are some of the symptoms you are most concerned with these days. About 5 weeks have passed since your pregnancy and you should gradually take care of your nutrition and the fetus inside you. To deliver food to the fetus and its growth, the body will produce more blood and as a result you will soon get tired. Of course, these symptoms are not the same in all mothers and its extent depends on the physiology of the body. How will your body change this week?

Changes in the mother’s body

From fertilization to childbirth, your body will undergo major changes. Hormones and you’re probably booming. Mood swings are very common this week, so make sure you get enough sleep, because there is nothing worse than being naughty and tired! Do you feel extraordinarily happy one moment and just as anxious the next? These are all part of the natural mood swings associated with pregnancy. You may experience joy, depression, anger, emotion, power, and insecurity in just one hour.

Your body’s hormones fluctuate a lot, so it’s only natural that your emotions should be the same, especially when big changes are taking place. Mood swings often peak in the following month and sometimes increase again in late pregnancy. You may be interested to know that about 10 to 12 percent of women experience depression during pregnancy – about the same number as women who experience postpartum depression. Be sure to call your doctor if you ever feel depressed for more than two weeks during your pregnancy.

Fetal status in the fifth week of pregnancy

This week, for the first time, your baby’s heart will start pounding! (Neither you nor your doctor can hear this sound, but it may be seen as a movement on the ultrasound.) Your little one is growing up! The fetus now has three distinct layers: the outer ectoderm, which will make up the nervous system, ears, eyes, inner ear, and many connective tissues; The endoderm, or inner layer that will become the internal organs, such as the intestines and bladder; And the middle mesoderm, which will eventually form the heart and circulatory system. In the coming weeks, the mesoderm will form into bones, muscles, kidneys, and genitals.

Although it’s hard to believe, your baby is still thinner than the English letter “I” this week. The fetus at this stage is less like a ball and more like a curved tube. One end of the tube will eventually become your baby’s head and the other end his legs. Between these two ends, the baby’s spine is forming, and by the end of the fifth week, a series of bumps will form on the back of the fetus. This is the beginning of the development of your baby’s central nervous system.

Like a small chicken, your baby has a yolk sac full of nutrients to help feed him. Blood flows through your baby’s primary heart into the wall of this sac and is returned. At this stage, your baby’s heart is a small tube, but by next week the left and right ventricles will form. Other major organs are also rapidly forming. The left and right hemispheres in your baby’s brain will form by the beginning of the second month, and his respiratory system will form a duct behind his face, developing as the baby grows, with 23 branches on either side as the lungs complete. It has branched out. The arms and legs are small buds, and the small arms may begin to form fingers at this stage. Your baby is finally visible to the naked eye.

Fetus in ultrasound images

Important stages of fetal development: The cells that make up the heart and central nervous system are growing.

What you see: The dark area is the fluid that fills the pregnancy sac. Eventually, this fluid will be replaced by a sac that contains amniotic fluid and your baby will live in it for a few months. The white circle in the liquid is called the yolk sac. Before the placenta is fully formed, the yolk sac plays an important role in providing the nutrients your baby needs to grow. Adjacent to the yolk sac, there are + signs of a very premature fetus. The sonographer measures the length of the fetus (head-buttock or CRL length) until it confirms, revises, or evaluates the fetal LMP estimated delivery date.

By the end of the first trimester, the yolk sac is completely reduced and will no longer be visible on ultrasound.

As mentioned, during the fifth week of pregnancy, the fetal heart begins to beat. Although at this stage the heart is in the form of a simple tube, it is the first organ in the body to begin to function. In the early stages of pregnancy, the fetal heart beats at 90 to 100 beats per minute. By the time the fetus is 8 weeks old, the heart rate will reach 120 to 160 beats per minute. The baby’s heart rate stays in that range until the end of the pregnancy. Although your baby’s heart is pounding, you will not be able to hear it for several weeks while seeing your doctor. Although it is possible to hear the fetal heartbeat using ultrasound, it is not very common to do so in these early stages of pregnancy.

Increased urination this week

As early as the fifth week of pregnancy, your uterus begins to expand, putting more pressure on your bladder. You may still feel the need to urinate even right after going to the bathroom, due to the pressure of the uterus on your bladder. Let’s look at the positive side of the issue, this multiple trips to the bathroom can act as a gentle exercise for you; So do not worry.

Although it may seem like a good idea to reduce your daily fluid intake to reduce the number of times you go to the bathroom, it can make you feel dizzy and is not strongly recommended.

Get enough sleep


No matter how you feel, remember that enough sleep is a sure boost to your mood. Eight hours or so of proper sleep creates a world of change in you, and right now you may feel like you are constantly exposed to sleep at work, in front of the TV, and even in the middle of your sentences. This is due to the increase in progesterone levels, lower blood sugar, lower blood pressure and increased blood volume.

Note: Pain or burning sensation when urinating during pregnancy is by no means normal. These symptoms may indicate that you have a common bladder infection, called bladder inflammation, which sometimes occurs with fever. If these symptoms occur, see a specialist doctor to test for the presence of bacteria in your urine and use safe medications for pregnancy.

Yolk sac: A sac enclosed by a membrane that is responsible for producing the nutrients needed by the fetus in the early stages of formation. The sac also acts as a primary circulatory system until the fetus is able to circulate internally.
