Pregnancy at 11 Weeks

Pregnancy at 11 Weeks
Your Body at 11 Weeks Pregnant

Don’t be surprised if people start mentioning that you have a certain glow. You will be feeling better and better as you head into your second trimester. And over the next few weeks, you will begin to show. Now’s a great time to do a little shopping for maternity clothes.

This is the time to do the blood test part of the first trimester screening. You can do the nuchal translucency ultrasound (NT) part of the first trimester screening this week or next.

Your Baby at 11 Weeks Pregnant

Your baby is now the length of a plum, and she’s moving more and more. Her hands and arms are almost fully functional, and the webs between her fingers and between her toes have gone away. Her kidneys are now producing the urine that makes up the amniotic fluid.


Your Medical Appointments at 11 Weeks Pregnant

You’re going to get good at peeing in a cup. During each prenatal exam, you will need to give a urine sample for testing. The urine test looks for signs of a bladder infection as well as the presence of sugar and protein in your urine. Bladder infections, also known as Urinary Tract infections (UTI), are very common in pregnancy due to the hormonal changes in your body. These changes will alter the urine make-up and allow bacteria to grow more easily. The bacteria that cause UTIs comes from your intestine and migrates to the bladder, it doesn’t come from your partner or other sources. UTIs during pregnancy are not usually accompanied with the burning and discomfort often noted when not pregnant. Some women will get UTIs for the first time when pregnant.

Your health care provider will offer you tests to look for Down's Syndrome and other genetic disorders at this time. If you’re planning to do the first trimester screen for Down's Syndrome, you should be doing the blood test part of it this week or next. The tests consist of a combination of two blood tests and one ultrasound. It is often called an "integrated screen." The first of the two "integrated screen" blood tests is usually done between 10 and 14 weeks of your pregnancy. The ultrasound is called a nuchal translucency (NT) and is usually done between 12 and 14 weeks of your pregnancy.

This ultrasound measures the amount of fluid behind the baby's neck (the nuchal area). There is evidence showing a direct connection between the nuchal thickness and the risk of having a baby affected with Down's syndrome.
The results from these two tests will be used to calculate an initial overall risk of Down's syndrome and other genetic disorders.

The second blood test of the "integrated screen," also known as the "AFP-Quad test" or "second trimester screen," is usually done between 15 and 20 weeks of your pregnancy. The result of this test will be incorporated with the results of the first blood test and the NT test and your final risk for Down's and genetic disorders will be calculated. The result will be given in the form of a probability (1/"number"). Over 90 percent of Down's syndrome babies can be detected in this way.

A detailed anatomical ultrasound (known as the "Anatomical Survey" or "level two ultrasound") will be done between 18 to 22 weeks to ensure that your baby is developing normally.
