15th Week of Pregnancy is How Many Months?

At 15 weeks pregnant, you are about 3 months into pregnancy. You are now at the beginning of the second trimester. The second trimester is ideally the middle of three months into the pregnancy, and it is at this point that people usually announce to the outside world about their pregnancy.

15 Weeks Pregnant Symptoms:

You will know it when you are in the 15th week of your pregnancy. Here are some 15 weeks pregnant body changes. Along with your body changes, some psychological changes begin too.

1. Weight Gain:

It is during this period that you will gain maximum weight. However, the weight might come down after the 15th week. It is during this period that the baby grows. The baby’s growth maximum happens in the second trimester. This is an important period of your baby’s growth, and at this point of time your body has adjusted to being pregnant but the baby is still growing, and due to this your body needs all the support possible to help your baby grow, and this is why you gain weight. The fat in your body provides the necessary nutrients for the baby as the stomachs amino acids break down your fat to provide nutrition for the baby; therefore, the more the fat, the healthier the baby. To overcome the extra weight you gain, indulging in quick and comfortable exercises will go a long way.

2. Bowel Problems:

The other irritating problem you could experience is your bowel movement change. During this period you may suffer from unwanted bowel problems and may run to the toilet more than usual, this is only because the baby is now able to process its food consumption at a better rate than before. The more it processes, the more it excretes causing you not only to feel hungry but also makes you run to the toilet more often than normal. Taking constipation medicines like Metamucil should take care of your bowel troubles in no time. A regulated diet can help elevate the metabolism and improve the movements.

3. Low Energy Levels:

You may run out of energy often, and you will sense it. In this period your baby is more active in your stomach, moving around a lot, and this will continue right through till the baby’s birth, and due to this, you will start feeling tired. This is because your child is attached to you, and the more energy the baby uses the more energy you will use. You will find that you have started sleeping longer, and when you wake up, it will feel like you hardly slept. Keep an energy drink around, and this will help you overcome your lack of enthusiasm.

4. Gastrointestinal Issues:

Another problem during the 15th month is gas issues. The gastrointestinal issue occurs because your progesterone levels are helping the gastrointestinal muscles to relax thus slowing down the process of your digestion. This issue can lead to burping and flatulence. To overcome this issue, you need to keep an eye on your food habits so that intake of calories can be minimized. This will make your digestion easier.

5. Insomnia:

A very common problem during pregnancy is insomnia. Studies show 70% of the pregnant women to be insomniac by the 15th week. The main reason behind this could be the pressure on your bladder by your growing belly, forcing your urination to be more frequent and waking you up. A larger belly also means having trouble finding the right position to sleep in. This can be another reason. The best way to overcome this is to take power naps as and when possible. This will give your body a better shot at resting. There are pregnancy pillows available in the stores now as well, so you can buy those to support your belly.

6. Heartburn:

The most common problem nowadays in pregnancy is heartburn. Excess salivation can make this issue worse. To avoid this, try to say no to sodas, spicy and sour foods. Also, try to minimise the production of gastric acid by keeping a check on your diet. 15 weeks of pregnancy care is, therefore, very essential.

7. Stuffy Nose:

Stuffy nose is a symptom you will find yourself falling prey to during pregnancy in the15th week. This is usually owing to the swelling of the nose membranes because of an increase in hormone production. The best way to avoid feeling congested in the nasal canal is to avoid situations that lead to a bad cold. Another alternative is to keep a warm bag around at all times and taking ginger tea every morning.

During the 15th week of pregnancy, there are significant developments that show the growth and development of your child. Constant ultrasound checkups every week will give you a detailed account of the week by week development of your baby.

What to Think About This Week:

Now that your womb is beginning to show more telltale signs of pregnancy, you will notice how neat your belly button looks.

Another change this week will be either activated milk glands that have already started the production or will start soon. Keep breast pads around so you can fit in inside the bra when needed. Your body will also feel like loosening itself, putting a strain on your skin. You need to find ways to control the stretch marks, so put that in your thought list as well.

How Do Your Baby and Belly Look Now?

15 Week Pregnant Baby Development:

Here are some changes that happen to the baby.

1. Functioning Kidneys:

In the 15th week, your baby’s kidney has entered into the functioning phase as the growth of organs also starts to develop. Due to this, your baby can urinate, thus allowing certain bacteria to get away from the body. The pee mixes with the liquid and finally excreted by the to-be mom. The kidneys play a vital role in the development of the baby.

2. Lungs:

The lungs of the baby are now expanding, allowing the baby to start the process of breathing. Though the lungs are expanding the baby will not breathe until they are born. The lungs until this time will expand and remain dormant. The lungs are one of the important organs of development in your baby’s body, and this happens in the 15th week of development.

3. Stomach:

The stomach is another development that your child goes through. Due to this development, your child can now process more and more food allowing their strength and growth to increase at a significant pace. The body starts accepting more types of food than before showing that the child is growing normally.

4. Immune System:

The immune system is the most important part of a person; therefore, during the 15th week of pregnancy, this particular development is extremely important. A healthy baby has a developing immune system during its 15th week of growth and now has enough white blood cells to fight off certain bacteria that would otherwise hamper its growth.

5. Hair:

An ultrasound will show that the baby has a level of hair on the head which was not there before. Though the hair is small, it still is a significant development showing that your baby is now sprouting hair. The hair can be of any colour and normally depends on the parent’s hair colour. Hair colour is normally hereditary. Hair is the first telltale sign of the complete development of your baby. A small layer of hair also grows on the entire body of the baby, though it is not visible the hair is there present on the baby’s skin.

6. Arms and Legs:

Your little one has his legs growing faster and longer now as compared to his arms. His joints are more flexible and can move now. You might have to wait longer for your next scan, which is usually scheduled around the 20th-week mark.

15th Weeks Activity:

Your belly is still in its growth period, so you need to find out ways of walking comfortably. In this phase, you also need to take care of your sleeping position. In 15th week you had to pay special attention to your sitting, sleeping and walking style. You also need to remember that you adopt good posture. The spine of your body should be as straight as possible, and when you get up, you should use something to maintain the balance and the centre of gravity throughout your body.

15 Weeks Pregnancy Diet and Exercise:

Your diet and exercise will have to fall in place now. Here are some of our suggestions.


1. Fruits and Vegetables:

A healthy diet will cure you and your baby of all the problems. Take the fresh fruits and vegetables that will give you vitamins. In my suggestion, take at least five different varieties of rich fruits and veggies throughout the week.

2. Raw Foodstuff:

Do not ever think that you should eat more food as my baby is still developing as this can lead to bloating. Try to eat raw food as much as possible. This keeps the nutrients preserved.

3. Iron:

Everybody needs iron to live a healthy life, so does a pregnant lady. Iron provides red blood cells to develop your baby. You should eat food like spinach, pulses, banana, meat etc. Tannins, on the other hand, found in tea and coffee is known to interfere with how the iron is absorbed by your body. Which is why the right thing to do is to make sure of is there is a decent gap between the tea or coffee and iron-rich foods.

4. Calcium:

In case you do not like meat or are a vegetarian, you need to make sure you have more calcium and iron since these are the two main components apart from proteins and vitamins that are needed for your child’s development. Your doctor might advise you to eat dairy products, bread, leafy vegetables, raisins and nuts.

5. Vitamin C:

Absorption of Vitamin C can make it easier for your body to gain iron that you take. For this, you can have oranges and lemons among the fruits to boost up your levels. Taking Vitamin C supplements is not a wise idea given your condition.


The best exercises to work on during this time should be the ones that focus on your stomach and pelvis for a better body posture. A few exercises that can help you are:

1. Belly Breathing:

To do this exercise sit and cross your legs, give support to your back and keep your hands on the stomach. Inhale through your nose now and keep expanding your belly. Repeat for 5 times.

2. Squat:

To begin the squat exercise, hold some object like an exercise ball or a chair and stand away from it. Lower your body slowly and keep your weight mostly on your heels. Inhale and exhale while doing the same. Repeat 5 times. This exercise helps to correct your posture and give more area to the pelvic region for expansion.

3. Walking:

Every doctor asks you to walk during the pregnancy. This exercise not only keeps you active but also helps you to keep calm and relax and prevents negative thinking while spending time lying in your room.

4. Inhale & Exhale:

This exercise of inhaling and exhaling helps you strengthen your muscles so that they can help with your contractions at a later stage. To do this exercise, you inhale the breath through the nose and hold it in for a while. Then you exhale, and while doing so, you bring your abdominal back in and bring your navel close to the spine.

5. Stretching:

Stretching during pregnancy gives you the flexibility and strength in your legs. This exercise also releases muscle tension, thus giving instant relief to your sore back and pelvis.
