The baby now weighs about 1 1/2 pounds and is approximately 12 1/2 inches long. He makes breathing movements, but has no air in his lungs yet. At this point, fetal brain scans show response to touch.

Sometime soon, you’ll need to take a glucose screening test. You’ll drink a glass of glucose water (it tastes like an intense orange soda) at your next doctor’s visit. Then she’ll take a sample of your blood for testing.

Talk to your midwife or doctor about other ways to cope.
