Pregnancy Week By Week - 22 Weeks Pregnant

Editorial Team

At 22 weeks, your baby is about the size of a small cucumber measuring about 28cm long and weighing about 430g. Your baby’s facial features continue to become more distinct and the lips are now fully formed.

Your baby’s lungs are developing rapidly, and they will begin to make a protein called surfactant, which will help her or him breathe independently after birth.

The eyes have formed but the irises show no sign of pigmentation yet. The organ systems in your baby’s body are more functional and specialised and the pancreas continues to develop steadily.

Your baby's skin is covered with deep wrinkles, which will gradually disappear as more fat is laid down.

Some of the symptoms you would begin to experience:

  • Stretch marks
  • Protruding belly button
  • Increased vaginal discharge
  • Swollen hands and/or feet
  • Backaches
  • Hair growth
  • Trouble catching your breath

Stretch marks are probably going to start appearing at this stage and there is not much you can do about it. You could just make sure your skin is moisturized regularly to keep it supple.

Call your doctor if you experience vaginal bleeding or fluid leakage, fever, severe abdominal or headache pain, or blurred vision. If you’re starting to feel what could be labour pains and you’re unsure whether they could be Braxton-Hicks contractions or the real thing, call your doctor.
