Week 11: Your baby's reproductive organs are developing

By the 11th week of your pregnancy, all of your baby's organs are in place. She's ready to focus on growth. When you're 11 weeks pregnant, your baby is about 1-1/2 inches long, which is about the length of your thumb from the knuckle to the tip.

Here are some other facts about this phase of your baby’s development:

  • From now until your halfway mark at 20 weeks of pregnancy, your baby will increase her weight by 30% and probably will triple in length.
  • The blood vessels in your placenta grow larger to prepare for this time of accelerated growth in your baby.
  • During the 11th week of your pregnancy, your baby's ears move to their permanent position.
  • Your baby's reproductive organs are developing. But it's still a little early to find out whether it's a girl or boy — gender isn't clear on ultrasound until between the 16th and 20th weeks of pregnancy.

Your Week 11 nutrition and health

Fighting fatigue with good nutrition and more

When you're 11 weeks pregnant, eating healthy, exercising regularly, and resting still top the list for keeping you and your baby healthy. And it's OK to be tired or feel exhausted — most women are more tired than usual during pregnancy. Your body works hard to produce hormones and more blood to support your baby's developing body. And your body's high level of progesterone directly impacts how sleepy you are. 

Here are a few tips for fighting fatigue: 


  • Eat a balanced diet. It's more important now than ever to keep up with your iron and protein.
  • Remember to rest. It sounds simple, but you might be tempted to do more, not less, during this exciting time. Your body needs those naps or extra hours of sleep, so be sure to build them into your regular routine.
  • Avoid taking on extra commitments during this time.
  • Ask for help when you need it, whether it's around the house, on the job, or during your other activities.
  • Stay active. It might be hard to get motivated to move, but remember that regular physical exercise will leave you feeling more energized.
Feeling fatigued?
  • Make sure you are eating a well-balanced diet of lean proteins, leafy green vegetables, and fruits.
  • Munch on healthy, nutrient-dense snacks — not on empty-calorie foods.
  • Drink lots of water — 10 8-ounce glasses per day (dehydration will slow you down).
  • Take brisk walks.
  • Take naps.
  • Communicate your fatigue to your doctor. Your iron levels might need to be checked.

Is there a pregnancy glow? Yes
You've heard that expectant mothers almost glow and you might be experiencing this yourself. This "glow" is thanks to your increased blood volume, which can cause skin to look slightly flushed and full. In addition, your body's hormones increase the amount of oils on your face, causing skin to look smoother and have a slight shine. At this point you might want to consider switching to oil-free skin products, if you haven't already.
