All About the Second Trimester

Everything you need to know to sail through most women's favorite time of pregnancy


Calming pregnancy fears
Although many women feel upbeat in the second trimester, some are bothered by underlying fears about everything from what might happen during their labor and delivery, to their baby’s health, to whether they’ll be good mothers. Women who are undergoing prenatal tests may feel anxious until they learn their results. And it’s not unusual to feel panic with every new ache or pain, spotting episode or Braxton Hicks “practice” contraction. Talking with your doctor or midwife, childbirth educator and other new moms during this time can help ease these anxieties.

“The more you understand that the way you feel is common, the more you can relax about it,” Dunnewold says. But if you find yourself worrying more often than not, you may want to seek professional help: Anxiety and stress may be linked to low birth weight and preterm delivery and may have other negative effects on the baby’s health as well. That’s true on the job, too, so do your best to cut back on both psychological and physical stress at work.

Diary Of A Second Trimester
Writer Lu Hanessian continues her pregnancy journal.

Week 14 Morning sickness lifts. Want to dance naked in living room without drawing the blinds. Dust off 5-pound weights, do 15 bicep curls. Speak in full sentences. Re-acquaint self with broccoli sautéed in garlic.

Week 16 Morning of my amniocentesis. See baby on monitor for first time. Tears tumble into my ears as I lie on table. “Hi, baby,” I whisper.

Week 18 It’s a … boy! Our toddler son, Nicholas, is going to have a brother. Call family, tell friends.
Week 20 Halfway mark! Fly to Boston for girlfriend’s wedding. Wear a long black beaded dress. Feel like a gestating mermaid. Shake my booty.

Week 22 Second ultrasound. Husband Dave and Nicholas stand in front of monitor while doctor points out face, feet, hands. Suddenly Nicholas yells, “Hi, little brother! I’m yer big brother!” Dave and I bawl like newborns.

Week 27 In full-throttle waddle. A penguin mama. Baby is doing Riverdance in my belly. I’m feeling fit and fertile. Eartha Kitt meets Mother Earth.

Your Body
Now that you’ve got your energy and appetite back, start to focus on healthful lifestyle habits.

Eat right for two

Expect to gain about 12 pounds in the second trimester, though this can vary, depending on your prepregnancy weight, says New York OB-GYN Joanne Stone, M.D. Get an extra 300 calories a day from nutritious foods such as fruits, vegetables, whole grains and protein sources; drink at least eight glasses of water daily; consume at least 1,000 milligrams of calcium daily; and continue taking prenatal vitamins and avoiding potentially harmful substances.

Keep (or start) moving

The American College of Obstetricians and Gynecologists recommends that pregnant women exercise moderately for at least 30 minutes on most days. If you didn’t work out before, start slowly (with your doctor’s approval) by walking, swimming or pedaling on a stationary bike. If you’re already fit, continue your regimen, but adjust it to avoid spills.

Take it easy at work

If you’re usually on your feet all day, look for ways to sit down as often as possible: Prolonged standing may cause pregnancy complications.

Get into sex

You’re over the fatigue and nausea of the first trimester and not yet huge. Take full advantage of this window of opportunity.

Testing, Testing
Most prenatal screenings are conducted in the second trimester. Here are the most common procedures:

The Test: Multiple Marker Screening
What it’s for: Screens for Down syndrome and other chromosomal abnormalities, as well as neural-tube defects, such as spina bifida.
Who gets it: Nearly all pregnant women.
When it’s given: Weeks 15–18.
How it’s done: Blood test.
Risks and drawbacks: False-positive results reported among 5 percent of test-takers.
What you should know: The test detects 66 percent of babies with Down syndrome. An abnormal result indicates an increased risk for this congenital condition and is followed by amniocentesis. An elevated alpha-fetoprotein (AFP) level, one of the chemicals measured in the test, points to an increased risk of neural-tube defects, low birth weight and other complications and is followed by an ultrasound.

The Test: Amniocentesis
What it’s for: Screens for Down syndrome, trisomy 18 and other chromosomal abnormalities. Also identifies the baby’s gender.
Who gets it: Women who will be 35 or older when they deliver, who test positive on multiple marker screenings, or who are at risk of having a baby with a genetic disease or chromosomal abnormality.
When it’s given: Weeks 15–18.
How it’s done: A long, thin needle is inserted through your abdomen into the sac around your baby to withdraw a sample of amniotic fluid.
Risks and drawbacks: Can be uncomfortable and cause mild cramping or spotting. About one in 200 women will have a miscarriage.
What you should know: Amniocentesis is offered starting at age 35, which is when the risk for Down syndrome is equal to the risk of miscarriage from the test. To minimize risk, have it performed by a physician experienced in the procedure.

The Test: Glucose Screen
What it’s for: Screens for gestational diabetes, which affects about 5 percent of pregnant women. Women who are over 30, overweight, have had a large baby previously or have a family history of diabetes are at higher risk. Who gets it: Nearly all pregnant women.
When it’s given: Weeks 24–28.
How it’s done: Blood test one hour after drinking a sugar solution.
Risks and drawbacks: None reported.
What you should know: About 15 percent of all test results are deemed abnormal; if yours are, you’ll take a lengthier glucose-tolerance test at a later date. Approximately 85 percent of women with elevated blood sugar in the screening test turn out to have normal levels, says OB-GYN Stone.
