Your baby this week

  • Ears have moved to roughly their final position on the sides of the head
  • Eyes can sense light even though the eyelids remain fused shut
  • Leg bones are lengthening quickly, and the legs are now longer than the arms
  • Taste buds are beginning to form

Your body this week

  • Nasal congestion and occasional nosebleeds can happen as blood flow to mucous membranes increases
  • Appetite often picks up as nausea fades for many people

This week's tip: A conversation about a pregnancy-appropriate multivitamin is worth having with your provider if you haven't settled on one yet.

When to get help now

Call emergency services now or go to an emergency department now if you have sudden, severe tummy pain, pain in the tip of your shoulder, feel very weak, faint or dizzy, or have heavy bleeding that soaks a pad soon after putting it on. For lighter bleeding or spotting, or pain low down on one side, contact your doctor, maternity unit or an early pregnancy unit today.
