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.
