Pregnancy Week by Week: Week 11...
Week 11
What Is Happening To Your Body
To fully nourish your baby, weight gain is necessary. Over the entire pregnancy, doctors recommend that you gain 25 to 35 pounds (11.3 to 15.9 kg). During the first trimester, you should be gaining 1 to 2 pounds a month (up to 6 pounds this trimester).
Some women lose weight in the first trimester due to nausea and other pregnancy symptoms. Be sure to check with your doctor to see if your weight gain is on track.
As this week progresses, you may find that your appetite is returning. Remember that good nutrition is important for both you and your baby. Don’t forget to eat healthfully and take your prenatal vitamins.
Starting this week, your doctor can perform a chorionic villus sampling (CVS) test on you, which tests for chromosomal abnormalities and inherited disorders.
What Is Happening To Your Baby
Your baby measures about 1.8 to 2.3 inches (4.4 to 5.7cm) long from crown to rump, or about the length of a lime. Your baby weighs about 0.3 ounces (8.5 g).
Your baby will be growing rapidly over the next 9 weeks from roughly 2 inches (5.1 cm) to 6 inches (15.2 cm). With this rapid growth, the blood vessels in the placenta are increasing in size and volume to provide the baby with more nutrients.
Your baby’s head is also developing. At this stage, its size accounts for about half the body’s length! Its ears are moving toward to their final position on the sides of the head.
The baby’s eyes are still very wide apart and the eyelids are fused shut. The irises, the colored part of the eyes, are also developing.
Some of your baby’s organs are also almost complete including the pancreas, thyroid and gall bladder.
