If you have not already done a pregnancy test , this is the time. You can buy pregnancy urine tests from the supermarket or chemist which are almost as accurate as those used in doctor's surgeries.

By the time you are 6 weeks pregnant, the baby can officially be measured. Although measuring from head to feet makes sense, this is too inaccurate as the baby is curled up. Standard practice measures from crown to rump, and by week 6, an average size is 5-6 mm. The head is still very large relative to the body, but little folds are forming in the face and jaw. Small bud-like lumps on the sides will become arms and legs. Small cavities forming on either side of the head will become ear canals. Even facial features like eyes and nose are beginning to form. Despite all this activity, it is still not obvious to anyone but yourself that you are pregnant.

Physical Changes at 6 Weeks Pregnant

  • Intensified symptoms: You are probably feeling the same symptoms as last week, only more extreme - more nausea, more sensitivity to scents, more tiredness, and generally low energy. Be patient and do not fight Mother Nature.
  • Morning sickness: Nausea and vomiting are common at 6 weeks as pregnancy hormones surge. Eat small, frequent meals and keep crackers by your bedside.

Helpful Hints for Week 6 of Pregnancy

  • Take a pregnancy test: If you have not confirmed your pregnancy, now is the time. Home tests are almost as accurate as those used in clinics.
  • Continue prenatal vitamins: Keep taking your folic acid supplement and prenatal vitamins to support your baby's early development.
  • Rest when needed: Low energy is completely normal. Listen to your body and rest when you feel tired.
