In the week 18, your baby is
the size of a Cucumber
At week 18, your baby is growing fast and you may feel gentle movements. Stay active, hydrate, and enjoy this exciting time as you bond with your little one!
Congratulations on reaching week 18 of your pregnancy! This is an exciting time as your baby continues to grow rapidly. During this week, you may start feeling more energetic and notice significant changes in your body. Your baby is also becoming more active, and you might even feel those first flutters of movement.
Let's understand what's happening with your baby and your body during this crucial stage of pregnancy.
As you enter week 18, you may experience various physical and emotional changes. Some common symptoms include:
Increased energy levels
Many women report feeling a surge of energy during the second trimester, often called the "pregnancy glow."
Backaches
As your uterus expands and your centre of gravity shifts, you may experience lower back pain or discomfort.
Vein health and Leg cramps
Hormonal changes and added weight during pregnancy can contribute to varicose veins and occasional leg cramps, particularly at night. Additionally, pregnancy increases the risk of developing deep vein thrombosis (DVT).
Swollen feet and hands
Fluid retention is common during pregnancy, causing swelling in the feet, ankles, hands and fingers.
Nosebleeds
The increased blood volume during pregnancy can cause the delicate blood vessels in your nose to rupture more easily.
These symptoms can vary. If you experience pain or discomfort, visit your doctor for the best guidance.
At 18 weeks, your baby grows steadily and makes remarkable developmental strides. Here's what's happening:
Organ Development
Your baby’s organs are maturing, with the digestive system active and the liver producing bile. Bones like the legs and collarbone are hardening, strengthening your baby’s body.
Physical Features
Your baby's features are becoming more defined. The ears are in place and can hear sounds while the eyes move, and the retina can detect light. Your baby can move the jaw, make facial expressions, and yawn.
Weight of the Foetus
At 18 weeks, your baby is approximately the size of a sweet potato, measuring about 14 cm from crown to rump and weighing around 200 grams. This is a period of rapid growth and weight gain as your baby prepares for the following stages of development.
Movement of the Baby
One of the most exciting milestones during week 18 is the possibility of feeling your baby's movements for the first time. These initial sensations, often described as flutters or "quickening," can be subtle and easy to miss, especially for first-time mothers.
At week 18, your baby’s movements grow stronger! Discover exciting milestones, body changes, and prepare for your mid-pregnancy check-ups.
Besides the symptoms mentioned earlier, your body undergoes several physiological changes during week 18.
Breast Changes
Hormonal fluctuations can cause your breasts to enlarge with tiny bumps called Montgomery tubercles. As your body prepares for breastfeeding, you may notice a darkening of the areolas and more prominent veins due to increased blood flow.
Hair, Skin, and Nails
Increased blood volume during pregnancy can lead to thicker, more lustrous hair and healthier skin. However, some women may experience skin changes like darkening or pigmentation, particularly around the nipples and the line running from the navel to the pubic bone (linea nigra).
Respiratory and Cardiovascular System
As your blood volume increases, you may feel lightheaded or dizzy due to lower blood pressure. Your heart works harder to pump the extra blood, which can cause dizziness or occasional shortness of breath.
Uterus Size and Position
At 18 weeks, your uterus has expanded and moved above your pubic bone. You may feel it as a firm, muscular ridge when you press gently on your lower abdomen.
Placenta Position
The placenta continues to develop and support your baby's growth by providing oxygen and nutrients. It also removes waste products from your baby's blood.
Pregnancy Gingivitis
Swollen, bleeding gums are common during pregnancy due to hormonal changes, leading to pregnancy gingivitis. Occasionally, a gum swelling known as a pregnancy granuloma may develop. You can consult your dentist for personalised advice and guidance.
Gentle workouts
Try swimming, pilates, yoga, or walking at a pace that allows you to hold a conversation.
Eat Healthy
Make sure to add variety in your meals to get energy, protein, vitamins, and minerals
Pregnancy Gains
Your pre-pregnancy weight and number of babies influence your second-trimester weight gain.
Baby’s nest
Get ready to welcome your newborn baby by building a nursery in your home.
Parenting prep
Learn more about parenting by taking classes on breastfeeding, infant CPR, and first aid.
Prenatal care
Attend local prenatal classes to learn about your pregnancy, childbirth, and newborn care.
During week 18, your doctor may recommend specific tests and screenings to monitor your health and your baby's development:
Routine checkup
Your doctor will measure your weight, blood pressure, and fundal height (the distance from your pubic bone to the top of your uterus) to ensure your pregnancy progresses uneventfully.
Anomaly scan
Also known as the anatomy or anomaly scan and mid-trimester ultrasound, this detailed scan is usually performed between weeks 18 and 22. It provides a detailed anatomical assessment of the fetus, examining the heart, bones, kidneys, and brain.
It also includes screening for anomalies in fetal development and overall growth. The scan evaluates the placenta position (to rule out placenta previa), checks the umbilical cord for proper blood flow, and monitors amniotic fluid levels.
Additionally, it measures the cervical length and observes fetal activity to ensure the baby’s well-being.
Maternal serum screening
Also called the Quadruple test, this blood test, typically done between weeks 15 and 20, checks for neural tube defects, abdominal wall abnormalities, and chromosomal disorders like Down syndrome or Patau syndrome. It is advised only if medically indicated.
Amniocentesis
This prenatal test is usually done between 15 - 18 weeks to check for chromosomal abnormalities and neural tube defects. It may be recommended if earlier tests show abnormal results or if there’s a family history of neural tube defects. This test carries a slight risk of miscarriage and hence is only done if medically necessary and the benefits outweigh the risks.
Yes, it's normal, especially if this is your first pregnancy. Some women may not feel movements until around 20-22 weeks. If you have any concerns, talk to your doctor.
Yes, in most cases, exercise is safe and beneficial during pregnancy. Low-impact activities like walking, swimming, and prenatal yoga are excellent choices. However, always consult your doctor before starting or continuing any exercise routine.
Focus on a balanced diet rich in fruits, vegetables, whole grains, lean proteins, omega-3, and healthy fats. Key nutrients include folic acid (found in leafy greens), calcium (from dairy products or fortified foods), and iron (from red meat, beans, or fortified cereals). Avoid high-mercury fish, raw or undercooked meats, excessive sugar, and processed foods.
Yes, back pain is a common complaint during pregnancy, especially as your uterus grows and your centre of gravity shifts. Gentle exercises, proper posture, and supportive footwear can help alleviate discomfort. If the pain is severe or persists, consult your doctor.
Talking, singing, or reading to your baby can help create a strong bond, even though they can't respond. You can also gently massage your belly or play soothing music. Involving your partner in these activities can further strengthen the connection with your growing baby.
Your doctor will check your weight, blood pressure, and fundal height. They may also listen to your baby's heartbeat and discuss any concerns or questions you have. If you're due for the anomaly scan or maternal serum screening, these tests will be scheduled or performed during this visit.
In most cases, travel is safe during the second trimester. However, it's essential to consult your doctor before making any travel plans, especially if you have a high-risk pregnancy or any underlying health concerns. Stay hydrated, take frequent breaks to stretch your legs, and wear comfortable, supportive clothing during your journey.
