Pregnancy at 10 Weeks

Pregnancy at 10 Weeks
Your Body at 10 Weeks Pregnant

For many women, nausea and fatigue begin to ease up during this week. When you go for your prenatal visit, you may be able to hear your baby's heartbeat with the Doppler, a small handheld instrument with a microphone-like probe that is gently pressed against your lower abdomen. Don't worry if you can’t hear your baby's heartbeat yet; it may still take a couple weeks.

Your Baby at 10 Weeks Pregnant

Your baby is now about the size of a small cherry tomato. His head is very large and makes up about half of the baby. Most of his organs have now been fully developed. Your baby is now swallowing the amniotic fluid and producing urine. Most of the amniotic fluid is, in fact, baby pee. His nails are starting to form, and his limbs can bend. Your baby moves extensively, although you may not be able to feel it for several months. However, if you get an ultrasound and your baby is awake, you may get to see him moving.

Your Medical Appointments at 10 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. If you would like to know the exact genetic makeup of your baby, you may consider Chorionic Villous Sampling or "CVS." This test is usually done between 11 and 13 weeks of your pregnancy and is an alternative to an amniocentesis.
