Pregnancy Week 19: Uterine Size and Round Ligament Pain

Symptoms

• More Noticeable Fetal Movements
  You may feel small taps, bubbles, or flutters in your abdomen.
  Movements will be more noticeable if this is not your first pregnancy.
• Lower Back and Hip Pain
  The growth of the uterus creates pressure on the spine and pelvis.
  Maintaining good posture and doing gentle exercises can help reduce discomfort.
• Leg Cramps
  These may appear especially at night due to pressure on the nerves and blood circulation.
  It is recommended to stretch your legs before sleeping and stay well hydrated.
• Skin Changes
  The linea alba, a dark line on the abdomen, may appear due to hormonal changes.
  Some women experience skin spots (melasma or chloasma) on the face. Using sunscreen is key to preventing them.
• Increased Vaginal Discharge
  It is normal for discharge to be more abundant and clear or white in color.
  If there is a foul odor, itching, or a change in color, it is important to consult a doctor.
• Increased Sensation of Heat and Sweating
  Increased blood flow and hormones can make you feel warmer.
  Wearing cool clothing and staying hydrated will help alleviate this sensation.
• Pressure or Slight Pain in the Lower Abdomen
  A feeling of heaviness or pressure may be felt due to the growth of the uterus.
  If the pain is severe or persistent, it is important to see a doctor.
• Constipation and Heartburn
  Pregnancy hormones slow down digestion, which can cause bloating and stomach discomfort.
  Consuming fiber, drinking enough water, and eating light meals helps improve digestion.

Baby’s size

At week 19 of pregnancy, the baby measures approximately 15 to 17 cm from head to toe and weighs around 250 to 300 grams. Their size is similar to that of a large mango or a medium tomato.

• Baby’s Changes and Development
  Growth and Proportions
  Their body continues to grow and is more proportionate in relation to their head, which until now was larger. Their limbs are more developed, and their movements are more coordinated.
• Sensory Development
  Their hearing is more developed, so they can hear outside sounds, including your voice, your heartbeat, and intestinal noises.
  Their sense of taste is also evolving, and they can detect the flavors of the amniotic fluid, influenced by the foods you consume.
• Vernix Caseosa
  Their skin begins to be covered with vernix caseosa, a white, creamy substance that protects them from the amniotic fluid and prevents their skin from drying out.
• Nervous System and Brain
  Their brain continues to form more complex neural connections, allowing for improved coordination and reflexes.
  They can make more precise movements with their arms and legs, and even bring their hands to their mouth.
• Lung Development
  Although they are not yet fully mature, the lungs begin to produce surfactant, an essential substance for their development and for breathing outside the uterus.
• Formation of the Uterus and Eggs in Female Babies
  If you are expecting a girl, by this week her uterus has already formed and she has millions of eggs in her ovaries.

What Should You Do?

• Perform the Morphology Ultrasound
  Between weeks 18 and 22, it is recommended to have a morphology ultrasound, a detailed study that evaluates the development of the baby and their organs.
  During this ultrasound, you could also find out the baby’s sex, if you do not already know it.
• Maintain a Healthy Diet
  Ensure you consume enough protein, calcium, iron, and fiber to support the baby’s development and avoid discomforts like constipation.
  Avoid ultra-processed foods and reduce the consumption of sugars and saturated fats.
• Stay Well Hydrated
  Drinking at least 2 liters of water a day helps maintain good circulation and prevents fluid retention.
  It also helps reduce the risk of urinary tract infections and improves intestinal transit.
• Practice Safe Exercise
  Stay active with exercises suitable for pregnant women, such as walking, swimming, prenatal yoga, or pilates.
  Avoid high-impact exercises or those that involve a risk of falling.
• Monitor Weight Gain
  At this stage, weight gain is more evident, but it is important that it be progressive and healthy.
  Consult with your doctor about how much weight gain is recommended in your case.
• Skin Care
  Use moisturizing creams with vitamin E and collagen to prevent the appearance of stretch marks on the abdomen, breasts, and hips.
  Apply sunscreen to avoid skin spots, such as melasma.
• Listen to Your Body and Rest Well
  It is normal to feel more tired due to the baby’s growth and hormonal changes.
  Sleep at least 7-8 hours and adopt comfortable positions, preferably on your side with a pillow between your legs.
• Manage Stress
  Practice relaxation techniques such as deep breathing, meditation, or gentle stretching.
  Avoid situations that generate anxiety and seek moments of rest and tranquility.
• Consult a Doctor if There Are Unusual Symptoms
  If you experience intense abdominal pain, bleeding, severe swelling, or a decrease in fetal movements (if you were already feeling them), consult your doctor immediately.
