We have prepared a great article for you about the 15th week of pregnancy. 🙂 We wish all mothers-to-be a pleasant reading in advance.
You have arrived at the 15th week as time continues to flow rapidly since the exciting day you learned you were pregnant. Now, as your belly grows, it becomes clear that you are pregnant enough to be noticed by your loved ones.
In addition, your baby will accelerate his growth as of this week. For this reason, you will see it differently at each doctor’s check and you will be surprised at what you see. So, what awaits you and your baby at the 15th week of pregnancy?
Baby at 15th Week
Your pregnancy is now more comfortable than the first weeks. The physical and hormonal changes experienced will of course add to you, but the problems you experience in the first weeks are significantly alleviated in the 2nd trimester. While you are trying to adapt to pregnancy, the 15-week-old baby does not sit idle, it grows and develops rapidly.
How Big Has My Baby got?
It is quite natural to wonder how much your baby has grown every time you go to the doctor’s checkup. You can be sure that this excitement will continue to increase until the birth.
The weight and height of the 15-week-old baby is expected to be as in the table below.
This information is for reference. If you encounter different values when you go to the control, you don’t have to worry. Because the calculations are based on the estimated time of fertilization, and if your fertilization time is different from the predicted, fetal values will also change.
If we accept the 15-week baby information as a reference, we can say that your baby has reached the size of a large orange as of this week.
Development of Systems and Newly Acquired Skills
Your baby, which will be called a fetus until birth, experiences a new development and change with each passing week, even day by day. In this process, the organs that continue their development gradually begin to function. Let’s examine the details of the 15-week-old baby’s organ and system development together.
Since the development of the brain will continue until birth, the brain appears in a more developed state every week than the previous one. Nerve cells continue to develop at the same rate. With the formation of the fatty layer called the myelin sheath, the number of movements your baby will make increases.
The circulatory system
As of this week, the placenta, which is quite developed, works to fulfill its task. The job of the placenta is to ensure the exchange of substances between the mother and the baby. In addition to the blood circulation, other necessary substances also reach the baby from the mother in this way. For this reason, you should pay attention to every food you consume and stay away from harmful foods.
Meconium, which will be your baby’s first poop, needs a little more time to settle in the colon.
The lungs, which continued to develop in the previous weeks, continue to branch and divide as of the 15th week of pregnancy. Also, the glands in the lungs begin to secrete mucus. He continues his breathing practices this week as well.
Support and Movement System
Your baby was starting to move. As the bone and muscle structure gets stronger, the intensity of these movements will continue to increase. In addition, since the nervous system continues to develop, movements begin to occur voluntarily, not reflexively. Although involuntary movements continue in facial mimics, they can stretch their facial muscles by making gestures such as laughing, getting angry, and being surprised.
Kidneys, one of the parts of the excretory system, had started to work in the previous weeks. They continue to develop and work in the same way this week.
As you move towards the end of the 4th month, in a pregnancy where everything is going well, you can actually find out the gender of the baby at 15 weeks. However, your baby may be shy or not in the right position for viewing. For this reason, your doctor does not want to tell you the gender of your baby without being sure. You have to give him some time or have some patience for the right time to come.
While your baby’s immune system continues to develop, the amniotic fluid protects him. Since it is such a protection shield, the development of the immune system will proceed a little slower than other systems.
15 Week Baby's Movements
Your baby, whose skeletal and muscular systems continue to develop, can now move all his joints more easily and stronger. Although the bones will continue to harden until birth, they will not lose their flexible structure for a comfortable birth. We know you look forward to the day when you can feel your little one’s movements as your pregnancy progresses.
At 15 weeks, the baby’s movements reach a palpable level. However, it is quite common for these movements to be mistaken for gas pains in first pregnancies.
Sense Organs and Developmental Characteristics of the 15-Week-Old Baby
As your baby’s vital organs continue to develop and work, their senses also develop. The tongue, eyes, ears, skin, and nose continue to grow and become more responsive to stimuli. So, if you are wondering how much your baby’s sense organ has developed as of the 15th week of pregnancy, let’s continue…
Eye and Sight
His eyes are still closed. However, even with his eyelids closed, he is able to notice the incoming lights even when he is in the womb. Around the 23rd week, the eyes will begin to open.
Ear and Hearing
The hardening of the bones in the ear in the previous week indicates that there is little time left for the hearing sense to start working. The ears are almost in their proper position. A little more time must pass before he can hear the sounds of the outside world.
Skin and the Sense of Touch
The skin is still transparent. Hairs called lanugo to continue to form this week. You can even see the blood running through his veins under the thin skin beneath these feathers. Since your baby’s movements are about to reach a perceptible level, they may shift in the other direction when you touch your tummy.
Tongue and Taste
By opening and closing his mouth, your baby also swallows amniotic fluid. Along with the taste of this harmless liquid, it slowly begins to smell.
Nose and sense of smell
The nose is now very prominent when viewed from the profile. The sense of taste continues to develop along with the sense of smell. In a short time, these senses will begin to work fully.
Mom at 15 Weeks of Pregnancy
The growth and development of the baby also cause some changes in the mother. These changes can be physical as well as psychological, due to fluctuations in hormones. So, as a 15-week pregnant, what kind of changes await you this week?
One of the most noticeable physical changes of pregnancy is weight gain. Your baby has now entered a rapid growth phase and considering that he is growing 1.5-2 times compared to the previous week almost every week, it is inevitable for you to gain weight. It is important to keep your weight gain rate under control.
Breast enlargement and tenderness:
The breasts and their mammary glands continue to grow due to increased estrogen and progesterone hormones. You may feel tenderness in the nipple as well as pain. For this, you can talk to your doctor and use an ointment. It is also normal to have a milky white discharge from the nipples as the mammary glands enlarge.
Most expectant mothers say that morning sickness decreases during these weeks, and that their appetite is restored and their energy is restored. Some expectant mothers also state that nausea has just started in these weeks and that’s why they have difficulty. This shows that every pregnancy is a different process.
Urinary tract infection:
The 15th week of pregnancy is the period when some expectant mothers experience urinary tract infections. If you feel the need to urinate more than usual but can’t go out, feel burning when urinating, or have a fever, you may be at risk for this infection. If this is the case, you should contact your doctor immediately.
Many expectant mothers complain of heartburn during pregnancy. The main reason for this is the increase in progesterone and estrogen hormones. This increase relaxes the smooth muscles, including the digestive tract, and as a result, the digestive system slows down.
Thus, the food you eat is sent to the esophagus and the emptying of the stomach slows down. With this slowdown, it is aimed that the nutrients are absorbed by the blood circulation and reach the baby. As a result, heartburn may occur as a result of the growing uterus and stomach being pushed by other organs.
Groin and abdominal pain:
With pregnancy, the connective and muscle tissues around the expanding uterus stretch. It is normal to experience pain and soreness during this stretch.
Blood pressure drop:
With pregnancy, there is an expansion in the circulatory system, that is, an enlargement of the veins. As such, the amount of blood returning to the heart decreases and leads to a drop in blood pressure. This is especially common in the first 24 weeks of pregnancy. After birth, it gradually returns to normal.
Pregnancy hormones also affect teeth and gums. As with other mucous tissues, the gums swell and bleed under the influence of these hormones. Again, the same hormones can pave the way for the formation of tartar and bacteria. If you are having a problem with your oral health, it would be right to consult a dentist by talking to your doctor.
Tips to Minimize Troublesome Pregnancy Symptoms
Although the second trimester is seen as the honeymoon of pregnancy, there are some situations that may disturb you during this period.

In addition, for some mothers, lying on their back also makes it difficult to breathe. That’s why you should get used to sleeping on your side already. In addition, you can try to sleep by placing a pillow on your back and raising it above the waist.
- During pregnancy, you may have difficulty sleeping deeply and uninterruptedly because of the need to change your lying position or to urinate frequently. This brings along the problem of insomnia. It will be good for you to sleep as much as you can during these periods, as the postpartum sleep pattern will change radically. For a quality and uninterrupted sleep, you can:

- Reading before bed helps you fall asleep easier. You can start reading books on baby care and development. As of the 15th week of pregnancy, travel will become easier. These trips can be difficult for you, as there is a lot of nausea before. The second trimester is a good time to make small vacation plans.
How Much Weight Should I Gain?

15 Weeks Pregnancy Checklist
- Amniocentesis is performed by taking a sample from the amniotic fluid in which your baby is present. 15-18 days of pregnancy. It is appropriate to do it between weeks.
- Quadruple screening test: In this test, your baby’s measurements are made with ultrasound imaging, and the blood sample taken from the mother is combined with ultrasonographic information and a risk calculation is made. This application is more of a diagnostic test and does not give definitive results. The 4-way screening test is performed on the 16th-21st days of pregnancy. You can do it in weeks.
If the double screening test you have had before at the 15th week of pregnancy has made you uneasy or if the result has caused you anxiety, you can have amniocentesis applied.

You can wait for the results of the 4-week screening test.
