By the middle of the first trimester of pregnancy, you are now 7 weeks pregnant. Most of these 7 weeks passed before you knew or were completely sure you were going to have a baby. Now it’s time to get ready for the new adventure ahead!
What kind of changes does the 7th week of pregnancy create for expectant mothers, how is your baby this week? We have compiled everything you can think of, from nutrition to exercises, from pregnancy symptoms to a checklist.
Your Baby at Week 7
When you reach 7 weeks, you may wonder at what stage your baby’s development is. Here are the answers to all your questions such as his weight, height, development of his systems and senses, what skills he gained…
How Big Has My Baby got?
Your baby has grown to the size of a blueberry this week.
Although it still seems very small, it has grown 3 times compared to last week. His skull, in particular, is highly developed and makes up a large part of his body. Thus, it allows the brain to grow rapidly. This rapid growth will continue in the coming days.
You may wonder how much a 7-week-old baby should weigh this week, but it’s still very difficult to comment on his weight. It is possible to get information about the physical properties of the ultrasound imaging and the size.
The 7-week-old baby’s height will be approximate as in the table below:
This value is an average value for embryos at 7 weeks. Your baby may not be this size. If your doctor states that the development of the embryo is good, you should not be stuck with the neck. Because it is normal for every baby to have some physical differences.
The Development of Your Baby's Systems and Newly Gained Skills
The first trimester is of vital importance for your baby. Because the basic formations of the system and its organs take place in the first 3 months.
So, let’s examine at what stage the organ and system development of the 7-week-old baby is.
The brain of the embryo is divided into 3 parts this week: forebrain, midbrain and hindbrain. Each part grows larger day by day. The main reason for this is that at least 100 nerve cells are produced per minute. These nerve cells will begin to connect with each other in the coming days.
The pituitary gland continues to develop.
The circulatory system
- The tiny heart continues to form, giving life to its tiny body by pumping blood frequently.
- The heart rate is 100-160 beats per minute.
- On ultrasound, your baby’s heart is visible as a black dot in the middle of his body.
At the 7th week of pregnancy, your doctor may not hear the baby’s heartbeat. In such a case, there should be no immediate concern and ultrasound control should be performed again the next week with the guidance of your doctor. In some pregnancies, the heartbeat can be noticed later.
This week, the digestive system of the embryo resumes its first formations, which began last week. The pancreas, gallbladder, esophagus, and stomach continue to develop.
- Your baby’s windpipe begins to develop.
- The lungs continue their cellular development.
- From the first day to the last, your little one’s respiratory system continues to develop.
Support and Movement System
- The arms and legs, which started to form last week, begin to curl and lengthen in the 7th week. These structures, which resemble a shovel, will become more prominent in the coming weeks.
- Joint structures in areas such as wrists, elbows and knees begin to form, but there is still time for full development.
- The tips of his fingers begin to form.
- Kidneys, one of the most important organs of the excretory system, begin to form and develop this week. However, its development is not yet at a sufficient level to perform urine production and discharge.
- Intestines are more prominent and continue to elongate.
Reproductive organs are not fully evident by the 7th week. There is maturation only at the cellular level. For this reason, you will have to wonder about the answer to this question for a while whether you will have a baby girl or a boy baby.
The organs of the immune system have not yet begun to develop. It protects your baby against all external factors until 40-42 weeks by realizing the formation of amniotic sac and amniotic fluid, which protects your baby from external factors.
Your Baby's Movements at Week 7
It is very difficult to view your baby’s movements on ultrasound at this time of pregnancy. It has a very microscopic structure with a length of about 12 mm, and even if it moves, it is not possible to view it. For this reason, 7-week-old baby movements are not felt and often cannot be seen.
Sensory Organs and Developmental Characteristics in 7 Weeks Old Baby
Your baby’s sense organs continue to develop, making more progress with each passing week. Like other organs, the basic structures of the sense organs develop during this period.
At what stage is the 7-week-old baby’s development when it comes to sense organs, here’s what your little one has learned this week, step by step…
Eye and Sight
The eye sockets and eyelids, which started to form the previous week, continue to develop this week. Eyelids are about to be completed.
Ear and Hearing
Ear cavities continue to develop. In the following weeks, it will regain its original appearance.
Tongue and Taste
Your baby’s tongue and mouth are starting to form, albeit small. It is still early for the formation of taste receptors on the tongue.
Nose and sense of smell
This week, the facial area becomes more prominent. The tip of his nose and nostrils begin to form and develop.
Skin and the Sense of Touch
Your baby’s skin has not yet formed its layers. This vulnerable structure is protected by surrounding it with amniotic fluid.
Mother at 7th Week of Pregnancy
As you reach the 7th week of your pregnancy, you may experience symptoms that will gradually remind you that you are pregnant. In this respect, the first trimester is the most challenging period for expectant mothers and creates the process that your body is trying to adapt to this new change.
If you are 7 weeks pregnant, let’s examine together what awaits you this week, what you should be prepared for.
What's Happening In Your Body?
Indigestion, swelling, and heartburn: Even though your baby is not big enough to define your tummy, you may notice that your belly is swollen when you look in the mirror this week. This is not caused by your baby; These are digestive problems that develop due to pregnancy hormones.
Indigestion and bloating, which are among the first signs of pregnancy, are among the first symptoms that appear in your body. Beta-HCG and progesterone hormones, which rise rapidly in the blood, can reduce bowel movements and cause a gas problems. It also changes the stomach pH, causing stomach acid to come into your mouth. The loosening of the valve between the esophagus and the stomach due to hormones also causes heartburn. These problems will ease a little in the coming months.
Mood swings: Hormonal changes can create some changes in your emotional state. As a result, with pregnancy, you are exposed to such an intense hormone level for the first time in your life. Sudden irritability and anger, excessive emotionality, unfounded fears and worries may increase this week.
Nausea: Some pregnant women may experience nausea this week, although it may appear in the following weeks. Nausea and vomiting, which are perhaps the most troublesome symptoms of pregnancy, usually disappear after the first 3 months.
Frequent urination: Increased fluid volume in the body, increased metabolic rate, and more waste processing in the kidneys can cause an increased urge to urinate. This problem may become a more common problem in the following weeks as the pressure of the baby on the bladder increases. However, fluid consumption should not be reduced.
Tips to Minimize Troublesome Pregnancy Symptoms
Symptoms that occur in the early stages of pregnancy can disturb expectant mothers.
Here are some practical advice for the mother at 7 weeks of pregnancy;
- Rearrange your diet to relieve nausea.
- Avoid consuming excessively oily, spicy foods.
- Put some pretzel-like snacks by your bed and try to quell your morning sickness with a salty snack when you wake up in the morning.
- Eat at frequent intervals and in small portions.
- Stop or reduce the consumption of tea and coffee.
- If you have more nausea and vomiting complaints, ask your doctor for a drug recommendation suitable for use by pregnant women.
- Try to find solutions to digestive problems by eating fibrous foods and consuming plenty of fluids.
- Try to drink fewer fluids before going to bed to avoid frequent urination. However, never completely reduce fluid intake. Choose day instead of night.
- Try to avoid smells that cause nausea.
How Much Weight Should You Gain?
Pregnant women are not expected to gain much weight in the first trimester. There are two reasons for this;
- Your baby has a low weight yet and the structures that feed him (uterus, sac, amniotic fluid, etc.) have not grown much. This does not make a significant difference in your body weight.
- Symptoms such as nausea, vomiting, and loss of appetite negatively affect the nutritional routine of expectant mothers and prevent weight gain. It can even be seen that some pregnant women lose weight in the first 3 months. This is normal.
For these reasons, the expectant mother may not gain weight. However, some pregnant women may gain some weight due to bloating or increased appetite.
Experts state that 1-2 kilos can be gained for 7 weeks of pregnancy. However, excessive weight gain can be prevented in the following weeks by taking care to maintain weight control, especially in the first months.
Nutrition plays an important role in all stages of pregnancy. Especially in the first months, the foundations of the baby’s organ development are laid, which raises the need for many vitamins and minerals to a higher level. Moreover, as time goes on, your baby will get what he needs from you, causing your warehouses to run out. For this reason, a diet consisting of foods with high nutritional value should be adopted from the first weeks.
The recommendations for nutrition at 7 weeks of pregnancy are as follows;
- Take care of a healthy and balanced diet. Make sure your meals include food from every food group.
- Try to eat a diet rich in vitamins and minerals such as iron, B12, folic acid, protein, calcium, magnesium, vitamin C, which have important roles in pregnancy.
- Make sure to drink 2.5 liters of water every day.
- Do not consume junk food products.
- Do not consume fatty and fast food foods.
- Be careful not to drink acidic and carbonated drinks. Give priority to drinks such as freshly squeezed fruit juices, ayran, mineral water.
- Make sure green vegetables are thoroughly washed and cleaned.
- Try to consume fish twice a week. However, when choosing fish, choose fish that does not contain heavy metals.
To exercise; not only to keep fit or lose weight but also to relax your body and mind. For this reason, you can use the advantages of exercising during a turning point in a woman’s life, such as pregnancy.

7th Week Pregnancy Checklist
We can list the things you need to do for the 7th week of pregnancy as follows:
