15 Weeks of Pregnancy – Symptoms and Fetal Development

By  | 

Normally, a pregnancy can last for around 40 weeks. It is usually divided into three trimesters. The early symptoms include absence of your regular periods, changes in the breast and nausea. By the second trimester, food cravings and mood swings are common. For the final trimester, you will mostly be tired through the day without even trying.

In the 15th week of pregnancy your baby is already developing and now his major organs such as his kidneys have developed allowing him to now urinate whenever he/she needs. Other organs such as the heart and the brain are also developing now allowing your baby to make a whole lot of new facial expressions which they would otherwise find it difficult to do. A strong heart allows the baby to move more eagerly than before. At this point soft kicks on the inner wall of your stomach are normal; the kicks are not yet strong enough as the baby is no bigger than five inches. This is an important week for the baby’s legs. The legs start growing during this week and this is why the kicks start.

Weight Gain:

During your pregnancy you will gain a significant amount of weight but in your 15th week you gain a more amount of significant weight but not to worry after this week your weight gain will subside. 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 take you a long way. Aside that, you can also keep a maintained diet and maximize the time you sit instead of lie down.

Bowel Problems:

During this period you may suffer with 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. And the more it processes the more it excretes causing you not only t feel hungry but also makes you run to the toilet more often than normal.

Low Energy Levels:

During 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. Do not forget to consult your doctor about what supplements are safe for your 15th pregnant week.

Gastrointestinal Issues:

Another problem during the 15th month is the gas issues. Your progesterone levels are sort of helping the gastrointestinal muscles relax, thus slowing down your digestive procedure. This in turn can lead to burping and flatulence. A good way to overcome the issue to keep your food habits monitored, so the intake of calories can be minimized with the nutrients kept intact. This will automatically make digestion easier without harming the baby.


You will find yourself having trouble falling asleep. Studies show as high as 70% of the pregnant women to be insomniac by the 15th week. The main reason behind this can 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 take power naps as and when possible. This will give your body a better shot at resting. There are pregnancy pillows available on the stores now as well, so you can buy those to support your belly.


Heartburn is quite common now, so try to keep a low profile with food that trigger discomfort like sodas, sour food and spicy ones. An issue that can make your condition worse is excess salivation. You might seem to find yourself spitting more than usual. Try to minimize the production of gastric acid by keeping your diet in check. That should work in your favor just fine.

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 the 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.

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.


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 parents hair colour. Hair colour is normally hereditary. Hair is the first tell tale 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.

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 and baby size will be about 4 inches long with 2.5 ounces weight. So you need to find yourself new ways to adjust your walking position as per your bump. You also need to focus on your sleeping position this week. Much like these two, working on your sitting style is another important thing to keep in mind since a good posture not only relieves pain, but also works on making your contractions smoother and less painful. The spine should be as straight as possible and when you get up, you should use something to maintain the balance and the center of gravity throughout your body. Talking of which, you will notice a shift in the center of gravity, so the right way to walk now is move your back a little backwards, doing which will keep the equilibrium intact.

15th Week Diet & Exercises:

1. Fruits and Vegetables:

Your diet this week needs all of the vitamins and fruits that there are. Your fair share of vegetables should also mark its presence in your food. The best suggestion here would be to try and gulp down five different types of fruits and veggies rich in all the nutrients you need through the week.

2. Raw Foodstuff:

Do not overeat thinking your child needs more to develop, since this can lead to bloating, which is in no way welcome in your situation. Try to eat raw vegetables instead. This keeps the nutrients preserved and hence makes the most of every foodstuff you consume. Your doctor might also suggest you with multivitamins if that’s your situation.

3. Iron:

Iron is an important nutrient for you since you need a lot of red blood cells to develop your little one. Food like spinach, lean meat, pulses and banana will be ideal for the same. 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 make sure of is there is a decent gap between the tea or coffee and iron rich foods.

4. Calcium:

In case you don’t like meat or are a vegetarian, you need to make sure you have more calcium and iron, since these are the two main nutrients aside from proteins and vitamins needed for the development of your child. Leafy vegetables, dairy products, bread, raisins and nuts should be taken regularly as advised by your doctor.

5. Vitamin C:

Taking vitamin C can make it easier for your body to absorb the iron you take in. You can buy oranges and lemons among the citrus fruits to boost your levels. Taking Vitamin C supplements isn’t a wise idea given your condition.


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

1. Belly Breathing:

For this exercise, sit and cross your legs. Support your back and keep your hands on the belly. Inhale through your nose now and keep expanding your belly. Repeat for 5 rounds.

The next best exercise would be to squat. To begin, 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 better your posture and gives more space to the pelvic region for expansion.

3. Walking:

Aside the above two exercises; you can also walk around every day for a bit. This not only keeps you more active, but also leaves you feeling less secluded than what it would have been otherwise if you spent the whole pregnancy lying in your room.

4. Inhale & Exhale:

Inhale through your nose and hold your breath. Exhale and while you do so, bring your abdominals back in, bringing your navel closer to your spine. This exercise helps a great deal in strengthening the muscles to help with your contractions later.
