Your Developments

  • The ligaments in your pelvic area will be loosening and stretching to accommodate the baby.
  • This may result in backache.
  • Constipation can be another result of the decelerated digestive process.
  • As food moves slower than usual through your intestines, more water is extracted leaving the stool drier and harder.
  • 1 to 1.5kg (2.3 - 3.5 lb) weight gain over the past month. On average 10 1/2 oz (300 gms) a week.

Pregnancy To Do's
