Pregnancy Facts - Week 11

Your baby's development in week 11 of pregnancy

At week 11 of pregnancy, your baby's arms and legs begin to move. Like an old man practicing tai chi in the park, your baby's limbs stretch and kick with an air of grace and fluidity.


It will be around week 16 when your baby's kicks and punches will be strong enough for you to feel them.

What's growing on this week:

  • Elbow, knee, shoulder and hip joints are beginning to take shape and assist with movement.
  • Fingernails are starting to grow on each of your baby's tiny little fingers. Toenails too on your baby's toes.
  • The first bit of light peach fuzz hair has begun to sprout form the top of your baby's head.
  • Underneath your baby's gums, teeth have begun to form. These won't grow out until after birth.
  • Nipples. Yes, nipples.
  • If your baby is female, ovaries. If your baby is male, not ovaries.


How big is your baby in week 11 of pregnancy

Your baby is now approximately 1.6 inches (4.1 centimeters) big and weighs 0.25 ounces (7.1 grams).

What's happening in week 11 of pregnancy

Stuff you might be feeling this week, which is more the same as the last several weeks:

  • Increased round ligament pains and muscle aches around your hips as your body continues to prepare itself for pregnancy.
  • Veins that are close to the surface of your body may become more visible and blue in color, depending on your skin tone. Your arteries have grown in diameter to help with the blood flow to and from the placenta.
  • Nausea. Seriously, when will it all end?
  • Super tiredness. You wake up in the morning and you're already ready for bed again.
  • Poor sleep at night because you constantly need to pee.
  • Constantly need to pee causing poor sleep at night.
  • Belly growth. This one shouldn't be a shocker to anyone.
