Εβδομάδα εγκυμοσύνης 15

At week 15, your baby is about 10-11 cm long and weighs as much as an apple. This week, revolutionary developments are happening in your baby's sensory world. Most impressively, even though your baby's eyelids are still closed (and will stay that way until about week 27), they can now sense light from the outside. If a strong light is shone on your belly, your baby will likely be bothered by the brightness and turn away. This is proof of how complex their nervous system is becoming. Development isn't just limited to the eyes; the hearing process is also picking up speed. The tiny bones in your baby's ears have started to harden. This means that very soon, they will begin to hear your heartbeat, the rumbles of your digestive system, and even loud noises from the outside world. The skeletal system is also continuing to harden rapidly. The skeleton, which was mostly cartilage in previous weeks, is now turning into real bone tissue. Your baby is currently hiccuping, stretching, and sucking their thumb in the amniotic fluid. Although their skin is still very thin and transparent enough for blood vessels to be seen, they are moving quickly toward becoming a completely unique individual.

During these weeks when your energy is high, a surprising symptom might knock on your door: Pregnancy Rhinitis. You might notice that your nose is constantly stuffy or that you experience occasional nosebleeds, even though you aren't sick at all. This is caused by the increased estrogen levels and blood volume in your body. This combination causes the mucous membranes in your nasal passages to swell and produce more secretions. If you have started snoring at night or wake up with a dry mouth in the morning, this temporary condition is the culprit. Changes are continuing in other parts of your body as well. Since your uterus is now completely outside the pelvis, it is very normal to feel a firm and distinct curve in your abdomen. This growth is beginning to gradually shift your center of gravity. Additionally, your gums may still be sensitive due to increased blood flow, and mild bleeding—known as pregnancy gingivitis—may continue. If you feel more forgetful than usual, it means you are still experiencing the effects of Pregnancy Brain. Don't worry; it is very human to forget simple details since your body is currently spending all its resources on building your baby. Enjoy this week while being at peace with your growing bump.

During these weeks, as your baby's skeleton turns from cartilage to bone, calcium should be the star of your plate. Your baby gets all the calcium they need to strengthen their bones from you. If you don't get enough calcium through your diet, your body will start to pull this mineral from your own bones and teeth. This could lead to bone loss or dental issues in the future. Therefore, week 15 is the time to replenish your calcium stores. You don't have to rely only on milk and cheese. Yogurt, kefir, almonds, sesame seeds, broccoli, fresh figs, and dark leafy greens (especially arugula and garden cress) are wonderful sources of calcium. Remember that vitamin D is essential for calcium absorption; so, be sure to take the supplements recommended by your doctor and try to get 15-20 minutes of sunlight every day if possible. Additionally, to support your increasing blood volume, your water intake should stay at least 2.5-3 liters per day. Water doesn't just provide hydration; it is also your greatest ally in preventing urinary tract infections, which are common during this period. While your appetite is good, focus on these foods that support your baby's bone and dental health instead of empty calories.

This week, as your baby's hearing system begins to develop, it is a wonderful time to start communicating with them intentionally. Many expectant parents may find it unusual at first to talk to a baby who has not yet arrived. However, scientific data shows that babies can distinguish their mother's voice from other sounds, which often has a calming effect. Talking or reading aloud makes the invisible bond between you and your baby feel more tangible, allowing you to focus on the miracle inside. If speaking feels difficult, you can place your hand on your belly and listen to music together. These quiet bonding moments lay the foundation for the deep love that will grow after birth. By involving your partner, you provide your baby with the sense that a family is already waiting for them, strengthening your shared parenting journey.

Screening Tests The period between weeks 15 and 20 is an important screening window for your pregnancy follow-up. If you missed the first-trimester screening at week 12 or if your doctor recommends it, Triple or Quadruple Screening tests are performed during these weeks. These tests use a blood sample from the mother to assess the baby's risk for certain genetic conditions, such as neural tube defects and Down Syndrome. It is important to remember that these tests are a risk analysis, not a diagnosis. Maternity Shopping Regarding shopping, you might consider getting a pregnancy support pillow this week. As your belly grows, sleeping on your side can become more difficult; these pillows support both your belly and back, helping you get a good night's sleep. You can also enjoy your changing body by treating yourself to a stylish maternity dress this week. Having pieces in your wardrobe that make you feel beautiful will instantly boost your mood. Remember, every investment you make in yourself is actually an investment in your baby.

When you look in the mirror this week, you might notice a dark, vertical line running down from your belly button. This line is called Linea Nigra (Latin for "black line"). Don't worry, this is not a skin blemish or a permanent issue. During pregnancy, an increase in melanocyte-stimulating hormones causes more pigmentation in your skin. This line was likely there before but went unnoticed; it becomes darker and more visible during pregnancy. Weekly Tip: Don't fight the Linea Nigra. Trying to scrub it away or use chemical products can irritate your skin. This line will naturally fade and disappear a few months after birth once your hormone levels return to normal. You might also notice similar darkening on your nipples (areolas) and any freckles on your face. Continue using high-SPF sunscreen to protect your skin, as sunlight can make these dark areas even more noticeable. These marks on your body are like "natural tattoos" showing that you are carrying a new life. Embrace them and respect the incredible changes your body is going through.
