At a length of 10 cm (from the top of the head to the seat) your child has a weight of 50-70 grams, being the size of a larger apple.
Pregnancy at 15 weeks: how your baby grows
Its main activity is now swallowing the amniotic fluid; this process will help him to develop the alveoli in his lungs and digestive system.
The lower limbs grow larger than the upper limbs, starting to recover from the difference in existence. Baby can move all the joints and all the segments of the limbs. He can open his hand, he can move his fingers and he can "bike" with his feet. Sweat glands are now formed.
In week 15, the eyebrows and hairs on the baby's scalp begin to appear. If it is brown, at this point the hair follicles may begin to form the pigment that is responsible for the dark color of the hair.
The ears, which have almost reached their final position (they are still positioned slightly below), begin to look like those of a baby. And the eyes get a more pronounced contour.
The baby now has skin so thin that he can see the blood vessels. For this reason it looks very red.
During this week, bones and bone marrow (which make up the bone system) continue to form. And the muscles continue to grow.
The eyelids are closed and the eyes are also developing. The taste buds responsible for the sense of taste are in formation. At birth, the baby's eyesight is not very well developed, he can only see the shades of black and white much closer. In contrast, the other senses are well developed; the newborn hears well and has a developed sense of smell, so that shortly after birth he can recognize the specific smell of his mother's milk. Also the tactile sense is developed.
If you go to an ultrasound consultation, from this moment you can know with certainty the sex of your child. Do not be disappointed if the ultrasound fails to unravel this mystery. There are several factors that contribute to the finding of sex, among them being the clarity of the images and the position of the fetus during the ultrasound (it could be in a position where the sex cannot be determined).

What happens in your body in week 15 of pregnancy
By now you should have weighed about 2-3 kg. If you have gained a little more or less weight, do not worry about it. Women get fat in different ways.
In addition, if you are one of the women who is stressing for a few extra pounds, then it is very important to remember that what you accumulate as weight does not just mean fat (apart from the baby itself). Moreover, it is important to know that that extra weight is beneficial for you and your baby (obviously, as long as it does not exceed the indicated average).
Here is what the average recommended weight of 13-14 kilograms, accumulated during pregnancy, is actually formed:
- The baby - 3.4 kilograms
- Placenta - 680 grams
- The womb - 900 grams
- Amniotic fluid - 900 grams
- Deposits of fat, proteins and various nutrients (necessary for breastfeeding) - 3.2 kilograms
- Breast tissue (also for breastfeeding) - 900 grams
- Additional fluids throughout the body - 1.8 kilograms
- Additional blood - 1.8 kilograms.
So, whenever you feel fat during pregnancy, remember the above rows, and think that at least 5 kilograms you lose even at birth. And most of the rest can go away without any effort, with the breastfeeding.
Common symptoms at 15 weeks of pregnancy
During this period different normal symptoms may occur during pregnancy. For example: if you have a stuffy nose, it may be due to the increased amount of estrogen that can cause edema in the mucous membranes, leading to increased mucus production. This symptom can accompany your entire pregnancy and you do not have too many resources to solve the problem.
Make sure the house is at optimum humidity (you can put a pot of water on the radiator to slightly humidify the air in a room) and hydrate well. You can use nasal solutions based on seawater or physiological serum from the pharmacy to clean your nose. Many of the nasal sprays found in pharmacies for nasal decongestation should not be used in pregnancy. So, before using any pharmaceutical substance, ask your doctor.
Other causes of the stuffy nose are colds and allergies. If these problems bother you and you cannot control them with remedies at hand, ask your doctor what medicines you can take.
Another common symptom in pregnant women is epistaxis - bleeding from the nasal mucosa. Many pregnant women are scared if they notice that they have a small nasal bleeding, but they must know that the bleeding is normal (in small quantity), and that it is due to the fragility of the small blood vessels in pregnancy. If the bleeding is abundant, then clearly you should ask your doctor.
Colds and allergies may be more common in pregnancy due to decreased immune system. In pregnant women, immunity is low to allow for the development of the baby. The most important thing is to avoid getting sick - avoid crowded places and sick people. Wash your hands frequently, the most common way of transmitting infectious diseases is through contact with dirty hands. If you are allergic to something specific, avoid as much exposure as possible to that allergen. You should also avoid irritants such as cigarette smoke, aerosols and alcohol.
Many pregnant women and their partners worry about the health of the child and his education. It is normal, but try to fully enjoy this moment of pregnancy. This trimester is a wonderful time for most pregnant women.
Infections during pregnancy
UTI (Urinary Tract Infections) are the most common bacterial infections during pregnancy. Usually, the bacteria in the digestive system and around the anus reach the level of the urethra, from where it ascends to the bladder, where it continues to multiply. Thus, they can sometimes lead to bladder infection, called cystitis.
These infections are favored by the increased level of progesterone, which prevents optimal emptying of the bladder and relaxes the urinary tract.
Urinary tract infections are dangerous in pregnancy and require treatment. Pregnant women who have urinary tract infections have an increased risk of preterm birth and developing kidney infections.
The symptoms of UTI are: pain or stinging in urination and abdominal or pelvic pain. Urine can be disruptive and you can have imperious urination (the need to clear the bladder immediately). If you have these symptoms it is advisable to seek medical advice. It will recommend you to make a summary of urine and a uroculture, tests that detect the presence of bacteria in the urine.
If you really have a urinary tract infection, after a lab test you can find out what antibiotic you can take to treat it. Several antibiotics are allowed during pregnancy and are considered safe for the child (penicillins, amoxicillin, cephalosporins).
Bacterial vaginitis (VB): This infection is caused by the overgrowth of bacteria that commonly exist in the vagina. This may or may not be symptomatic.
Symptoms may be: white or gray secretion, foul odor (the smell is more intense after intercourse), irritation or itching (itching) in the vagina and vulva. At least 50% of women with bacterial vaginitis have no symptoms.
And this infection must be treated during pregnancy. Many doctors believe that bacterial vaginitis can increase the risk of preterm birth. The treatment is usually local, with antibiotic eggs inserted into the vagina. The presence of infection can be detected by an analysis of vaginal discharge.
Mycoses (infections caused by fungi or fungi) are common infections in pregnant women. They are infections caused by Candida class fungi. These are found in the vagina in about 33% of women.
Fungi become a problem when they grow very fast and thus inhibit the growth of other naturally occurring germs in the vaginal flora. The increased level of estrogen during pregnancy leads to increased glycogen production in the vagina, which favors the multiplication of fungi. (Some studies show that estrogen has a direct effect on fungi, helping to multiply them and to better attach to the vaginal walls).
Fungal infections also need to be treated during pregnancy, especially because they cause discomfort to the mother. Treatment is usually done with ova with antifungal substances inserted into the vagina. The infection can be detected by an examination of vaginal discharge.

Bacterial vaginitis is associated with a higher frequency of premature births and premature rupture of membranes. If there is already another risk for preterm birth, the doctor will perform a screening test for infections, and if it is positive, then he will indicate antibiotic treatment. If you are not a patient with a known risk and you have no symptoms, this test will not be done.
A treated urinary tract infection will not cause other problems. However, if this condition remains untreated, it can worsen and cause other infections in the kidney, such as pyelonephritis - a serious condition that can also increase the risk of preterm births.
If you have a urinary tract infection, your doctor will prescribe antibiotics that can be given during pregnancy. The symptoms will improve in a few days. It is important to follow all antibiotic treatment, so that the bacteria is completely eliminated from the body.
A fungal infection (a fungus) does not affect the child. If you have a fungal infection during vaginal birth, there is a chance that the newborn will get in touch with the disease. These infections are referred to as aphthus and can be recognized as white lesions in the buccal mucosa. However, it is not a serious condition and can be easily treated.
How can I prevent these infections?
- He wears cotton clothes and avoids tight pants;
- Sleep without underwear for the genital area to be ventilated;
- Avoid long showers, jacuzzi, and do not stay long in a wet bathing suit;
- Avoid scented soaps, scented detergents, sprays and shower gels;
- Always wipe from the front to the back, to avoid bringing the bacteria around the anus into the urethra;
- Eat yogurt that contains Lactobacillus acidophilus, which will help you restore balance in the vaginal flora;
- Drink at least 8 glasses of water per day;
- Drink cherry juice - helps to stop the proliferation of bacteria;
- You urinate every time you feel it. When you urinate, lean forward to help completely clear the bladder.
Analysis and investigations in week 15 of pregnancy
If you have done all the necessary analyzes so far, you have nothing to do this week. It is important to talk to your doctor if you want to take the triple test.
The triple test (or sometimes the quadruple test, if inhibin A is analyzed) is a blood test that is recommended to be done between weeks 15 and 20 of pregnancy and that indicates the levels of three substances: estriol, human chorionic gonadotropin (HCG) and alpha-fetoprotein (AFP). Following the test, certain genetic disorders and congenital anomalies can be revealed.
Also, this week you can do tests for the detection of cystic fibrosis or some forms of congenital deafness in the following weeks. If you need to do amniocentesis, ask your doctor how you should prepare.
What to do in week 15 of pregnancy
