Blossoming Wonders: Week 18 of Pregnancy Unveiled

Baby Size at Week 18: Your little bundle of joy is now about the size of a bell pepper, measuring approximately 5.6 inches (142 mm) from crown to rump. They weigh around 6.7 ounces (190 grams) and continue to develop their unique features, such as fingerprints and toenails.

Changes and State in the Mother’s Body: As you enter week 18, you may notice that your baby bump is more pronounced, and your abdomen continues to expand. Your uterus has grown to about the size of a cantaloupe, and you may start experiencing round ligament pain as the ligaments supporting your uterus stretch. Additionally, you might feel your baby’s movements becoming more distinct and frequent.

Common Symptoms:

  • Heartburn: Hormonal changes and the growing uterus can cause the valve between the stomach and esophagus to relax, leading to heartburn. Eating smaller, more frequent meals and avoiding spicy and greasy foods can help alleviate this discomfort.
  • Leg cramps: Many pregnant women experience leg cramps, especially at night. Stretching your legs before bed and staying hydrated can help prevent or reduce the frequency of leg cramps.
  • Swollen ankles and feet: The increased blood volume and pressure on your lower body can cause swelling in the ankles and feet. Elevating your legs, wearing comfortable shoes, and avoiding prolonged standing can help reduce swelling.
  • Skin darkening: Some women may notice dark patches on their skin, such as the linea nigra, darkened underarms, or melasma (also known as the “mask of pregnancy”). These changes are typically temporary and fade after pregnancy.
  • Increased appetite: As your baby’s nutritional needs increase, you may find yourself feeling hungrier than usual. Focus on consuming nutrient-dense foods to satisfy your cravings and support your baby’s development.

Tips for Week 18:

  1. Stay hydrated: Drink plenty of water throughout the day to stay hydrated and help prevent swelling and constipation.
  2. Practice gentle exercises: Engage in low-impact exercises like swimming, walking, or prenatal yoga to stay active and relieve muscle tension.
  3. Take care of your skin: Protect your skin from the sun by using sunscreen with a high SPF and wearing protective clothing. Moisturize regularly to help alleviate dryness and itching.
  4. Bond with your baby: Spend time talking, singing, or playing music to your baby. You can also try gently pressing on your abdomen to see if your baby responds to touch.
  5. Plan for maternity leave: Start discussing maternity leave options with your employer and understand your rights and benefits. Create a plan for your time off and organize any necessary paperwork.


  1. Can I dye my hair during week 18 of pregnancy?
    • While there is limited research on the safety of hair dye during pregnancy, most experts suggest avoiding chemical hair treatments, especially in the first trimester. Consider using natural alternatives or consulting with your healthcare provider before making any decisions.
  2. Is it normal to feel lightheaded or dizzy during week 18 of pregnancy?
    • Feeling lightheaded or dizzy can be common during pregnancy due to hormonal changes, increased blood volume, and changes in circulation. Take breaks, avoid standing for long periods, and make sure to eat regular, balanced meals to help manage these symptoms.
  3. When should I start preparing my birth plan?
    • It’s a good idea to start thinking about your birth plan during the second trimester, around week 18-20. Discuss your preferences with your healthcare provider, attend childbirth classes, and gather information to make informed decisions about your birth experience.
