18 Weeks Pregnant: A Comprehensive Guide to Your Pregnancy Journey

Congratulations on reaching 18 weeks of pregnancy! You have now entered the second trimester, a period marked by increased energy, reduced morning sickness, and a growing baby bump. This is an exciting time in your pregnancy journey, as you begin to feel more connected to your baby and witness their remarkable development.

Your Baby’s Development at 18 Weeks

At 18 weeks, your baby is about the size of a bell pepper, measuring approximately 5.5 inches in length and weighing around 6 ounces. Their facial features are becoming more defined, with prominent eyes, a small nose, and a delicate mouth. The baby’s fingers and toes are fully formed, and they are beginning to make small movements, such as kicking and stretching.

Your Body Changes at 18 Weeks

As your baby grows, so does your uterus. At 18 weeks, your uterus has expanded to the size of a grapefruit and is now located just below your belly button. This expansion can cause your abdomen to become more prominent and your waistline to thicken.

Other physical changes you may experience at 18 weeks include:

  • Increased breast size and tenderness
  • Darkening of the areolas and nipples
  • Linea nigra, a dark line that runs down the center of your abdomen
  • Increased vaginal discharge
  • Frequent urination
  • Constipation
