At 25 weeks pregnancy, both mother and baby are experiencing significant growth and changes. The baby becomes more active, with movements, kicks, and turns that are clearly felt. His body is developing rapidly, with stronger limbs, accumulating fat, and improving lung and brain functions.
For the mother, this stage brings noticeable belly growth, increased baby movements, mild back pain, swelling, and sleep challenges. Proper nutrition, hydration, rest, and regular checkups are essential to support both mother and baby. Understanding what to expect helps you navigate this stage safely and comfortably.
Baby at 25 Weeks Pregnancy
At 25 weeks pregnancy, the baby’s growth is faster and he becomes more active than before. At this time, the baby’s length can be about 33–35 cm and weight about 700–850 g. Although the baby’s skin is still a little thin, it is gradually starting to accumulate fat, which will help regulate body temperature after birth. The baby’s lungs are developing and he can take in amniotic fluid as breathing exercises.
The baby’s movements inside the mother’s belly are now felt more clearly and sometimes there may be a feeling of kicking or twisting. During this time, the baby’s brain develops rapidly and the nervous system becomes stronger. The baby’s hearing also improves, so he can understand some outside sounds. Adequate sleep, drinking water, nutritious food and regular check-ups are very important for the mother during this time.
25 Weeks Pregnancy Symptoms
25 Weeks Pregnancy is a very important stage for the mother and the baby. During this time, the baby grows rapidly and various physical and mental changes may occur in the mother’s body. Many new symptoms may be felt due to hormonal changes, increased baby movements, enlarged uterus, and excess body weight. However, most of the symptoms are normal and are common at this stage of pregnancy. Below are the main symptoms of 25 weeks of pregnancy in detail.
1. Increased belly size
At 25 weeks, the uterus rises a lot and the baby’s weight also increases rapidly. As a result, the belly feels bigger and heavier than before. Many mothers walk slower and feel more pressure on the stomach when standing or sitting. At this time, the skin on the stomach becomes tight and sometimes itching or discomfort may also occur.
2. Feeling more baby movements
The baby’s kicks, turns, or movements can be felt much more clearly than before. Sometimes it may feel like the baby is playing inside the stomach or suddenly pushing. In some mothers, the baby’s movements are felt more at night, because the mother is more calm at night and can easily sense the baby’s movements.
3. Waist and back pain
At 25 weeks, the pressure on the waist and back increases as the body weight increases. Due to the growth of the uterus and changes in the body’s balance, waist pain or tension in the lower back is often felt. Standing or sitting for a long time can increase the pain. At this time, light exercise, sitting in the right posture and resting can be beneficial.
4. Swelling of the legs (Swelling)
This week, many mothers may experience swelling in their feet, ankles or fingers. This problem occurs due to excess water accumulation in the body and increased blood circulation pressure. Swelling increases in hot weather or if you stand for a long time. However, if there is sudden swelling or swelling of the face and hands, it is important to seek medical advice.
5. Shortness of breath or difficulty breathing
As the baby grows, the uterus can push up on the lungs. As a result, it can be difficult to breathe when walking, climbing stairs, or working. This is usually a normal symptom, but if you have severe shortness of breath or chest pain, you need to see a doctor immediately.
6. Heartburn and indigestion
At 25 weeks, due to the effects of hormones and the pressure of the uterus, the production of acid in the stomach increases. As a result, heartburn, acid rising to the throat, or difficulty digesting food can occur. This problem can be aggravated by eating too many oily and spicy foods. Eating small meals repeatedly and not lying down after meals can help relieve the pain.
7. Frequent urination
As the baby grows, the uterus puts pressure on the bladder. This causes the urge to urinate quickly and makes you have to go to the toilet frequently. This problem is especially common at night. Although this is a common symptom, if you experience burning or pain during urination, it may be a urine infection, so it is important to see a doctor.
8. Stretch marks and itching on the skin
At 25 weeks, the skin on the abdomen, chest, and thighs begins to stretch, resulting in stretch marks. Sometimes the skin becomes dry and itchy. Regular use of moisturizers or oils during this time can provide relief. Drinking more water and keeping the skin moist also helps.
9. Fatigue and sleep problems
Although many mothers feel relatively well in the second trimester, fatigue may occur again due to weight gain at 25 weeks. When you go to sleep at night, you may be disturbed by the weight of the abdomen, the baby’s movements, or the pressure of urination. Adequate rest and sleeping on the left side are often comfortable.
How big is a baby at 25 Weeks Pregnancy?
At 25 weeks pregnancy, the baby’s size and weight increase significantly compared to before. Usually, at this time, the baby’s length can be about 34–36 centimeters (from head to toe) and the weight is around 650–750 grams. The baby’s body gradually starts accumulating fat, due to which the skin is not as thin as before. The baby’s arms and legs become stronger and movements are felt much more.

This week, the baby’s various organs learn to function better. The lungs gradually mature and begin preparing for breathing. The baby’s eyes can open and react to light. At the same time, the baby’s brain also develops rapidly, as a result of which its movements and reactions become more coordinated. At this time, the baby’s growth is very rapid, so the mother’s belly also appears larger than before.
What does a baby look like at 25 Weeks Pregnancy in the womb?
At 25 weeks pregnancy, the baby is taking on a more human-like appearance inside the womb. At this time, the baby is usually about 33–35 cm long and weighs about 650–750 g. His skin is still a bit thin and reddish, but as fat gradually begins to accumulate, the skin looks smoother than before. The baby’s facial structure is more defined—eyelids are formed and eyebrows and eyelashes are gradually thickening.
This week, the baby’s arms and legs are getting stronger and he is moving, kicking, and turning his body regularly. The baby’s fingernails are growing and hair is also starting to grow. Although the lungs are not yet fully developed, he can make movements such as sucking in amniotic fluid as a breathing exercise. In addition, since the baby’s ears are fully developed, he can hear outside sounds and respond to his mother’s voice.
25 Weeks Pregnancy is how many months?
A 25 weeks pregnancy is usually considered to be around 6 months. This is because pregnancy is often calculated by weeks, and there may be some differences when calculated by months. Generally, if we consider about 4 weeks in 1 month, 25 weeks is about 6 months and 1 week. This period is the last part of the second trimester of pregnancy and the stage near the beginning of the third trimester.
At 25 weeks, the baby’s growth is rapid and the mother usually feels the baby’s movements more clearly. During this time, the mother’s belly size starts to increase, mild pain, back pressure, fatigue or sleep problems may occur. Therefore, it is very important to drink enough water, eat nutritious food and have regular doctor’s checkups.

25 week ultrasound
Ultrasound at 25 weeks pregnancy is an important test that helps to understand the growth and health of the baby. During this time, the doctor observes whether the baby’s head, limbs, spine, heart and other organs are forming properly. In addition, the baby’s weight, length and position (head down or otherwise) are seen. Sometimes the baby’s facial structure, movements and heartbeat can also be clearly understood.
In addition, the 25 week ultrasound checks the position of the placenta, the amount of amniotic fluid and the function of the umbilical cord. If there is less or more water, or the position of the placenta is abnormal, then immediate action can be taken. This scan is very effective in ensuring the safe health of the mother and baby, so it is important to have regular checkups as advised by the doctor.
What to expect at 25 Weeks Pregnancy
During the 25 weeks pregnancy, several important changes occur in the body of the mother and the baby. During this period, the baby’s weight increases rapidly and the skin becomes less wrinkled than before due to the accumulation of fat in the body. The baby’s movements are felt more strongly and sometimes movements such as kicking or turning can be clearly understood. The baby’s hearing improves, so he can hear external sounds such as the mother’s voice or heartbeat. The size of the mother’s belly also gradually increases, which may cause some discomfort when walking or sitting up.
This week, mothers may experience symptoms such as back pain, swelling in the legs, sleep problems and heartburn. Mood swings or mental stress may also increase due to hormonal changes. Drinking enough water, light exercise, nutritious food and rest are very important. Regular doctor visits and monitoring the baby’s movements are important for a safe pregnancy during this time.
Your Pregnant Belly at 25 Weeks
At 25 weeks pregnant, your pregnant belly will start to look more defined and round than before. During this time, the uterus is growing rapidly and you may feel a tightening around your belly button. Many mothers experience itchy, dry, or stretch marks on their belly skin, which is completely normal. The weight of your belly can change your balance and make walking a bit uncomfortable.

Your baby’s movements are stronger this week, so you can clearly feel the kicks or movements in your belly. Sometimes you may feel a tightening or mild pain in your belly, known as Braxton Hicks contractions. Wearing comfortable clothes, drinking plenty of water, and getting regular rest can help make this period much easier.

Tips for 25 Weeks Pregnancy
25 weeks pregnancy means that you are now at the end of the second trimester. During this time, the baby’s growth is very rapid and many changes occur in the mother’s body. The belly is bigger than before, the baby’s movements are felt more and the body may experience fatigue, pain or sleep problems. Healthy food, adequate rest and regular checkups are very important during this time, as they play an important role in the health of the mother and the baby. With proper care, it is possible to spend this time more comfortably and safely. Important tips for 25 Weeks Pregnancy:-
1. Eat more nutritious food
At 25 weeks, the baby’s bones, brain and body tissues start forming rapidly. Therefore, it is very important to eat foods rich in protein, calcium, iron and vitamins at this time. Include more eggs, fish, milk, pulses, green vegetables, fruits and nuts in the diet. Drinking enough water is also important, as it keeps the blood circulation in the body and helps reduce constipation.
2. Ensure regular rest and good sleep
Due to the large belly at this time, sleeping problems may occur and fatigue may increase. Therefore, it is important to take regular rest. Lie down for a while during the day and try to sleep for at least 7-8 hours at night. Sleeping on your left side improves blood circulation and oxygen supply to the baby. If necessary, support your waist and abdomen using pillows.
3. Do light exercise (as per your doctor’s permission)
Light exercise such as walking, pregnancy yoga or stretching at 25 weeks helps to keep the body fit. This increases blood circulation in the body, controls weight and prepares the body for childbirth. Regular walking can also reduce swelling of the legs or back pain to a great extent. However, excessive pressure exercises should not be done at all and if there is any discomfort, it should be stopped immediately.
4. Take care to reduce waist and back pain
It is normal to have waist and back pain during this time due to the increase in abdominal weight. So, practice sitting and standing upright. Avoid lifting heavy objects at all. If necessary, you can use a waist support belt. Hot water baths or light massage often help to reduce pain, but it is better to do it after consulting a doctor.
5. Monitor the baby’s movements
At 25 weeks, the baby’s movements will be felt more clearly than before. It is normal to feel the baby’s kicks or movements several times a day. Do not ignore it if the baby’s movements suddenly decrease or do not occur at all. In this case, you should contact the doctor immediately. Regularly monitoring the baby’s movements can give an idea about the baby’s well-being.
6. Regular prenatal checkups
It is very important to see a doctor regularly at this time. Because at 25 weeks, blood pressure, sugar, hemoglobin and baby’s growth are monitored to see if they are okay. The doctor can do ultrasound or some tests, which help ensure the health of the mother and baby. Regular checkups can detect any problems in advance and solve them quickly.
7. Keep stress low
Due to hormonal changes during this time, mood swings, anxiety or restlessness may occur. Therefore, maintaining mental peace is very important. Get support from family and husband, do your favorite work, read books, listen to light music or meditate. Excessive anxiety can also affect the baby, so try to keep yourself as calm as possible.
8. Drink enough water and avoid constipation
Many mothers have problems with constipation, gas or acidity during this time. So drink at least 8-10 glasses of water a day. Along with this, eating fruits, vegetables and fiber-rich foods keeps the stomach clean. Reduce excess oily and spicy foods and fast food. This will improve digestion and keep the body light.
9. Take necessary vitamins and iron tablets regularly
It is very important to take the pregnancy vitamins, iron, calcium or folic acid that the doctor has given regularly. Because at this time, the baby’s bones become strong and the blood volume in the mother’s body also increases. Not taking the tablets regularly can cause weakness, anemia or other problems. So if you tend to forget, you can set a reminder in time.
10. Be aware of danger signs
If you experience any symptoms at 25 weeks, you should go to the doctor immediately. For example, bleeding, severe abdominal pain, dizziness, blurred vision, excessive swelling of the hands and feet, decreased baby movement, or a feeling like your water has broken. These can be signs of pre-term labor or other problems. Therefore, it is important to seek immediate medical attention without ignoring these symptoms.
Conclusion
By 25 weeks, the baby is more developed and starts to respond to sounds and light, making the womb experience more interactive. Movements are stronger, and the baby’s body continues to prepare for life outside the womb.
For mothers, managing symptoms like fatigue, heartburn, or swelling becomes important. Maintaining a healthy diet, light exercise, and regular prenatal visits ensures both your and your baby’s well-being. Staying informed and attentive to changes during this week supports a safe and enjoyable pregnancy journey, making this stage smoother and more reassuring for expectant mothers.
