11 Weeks Pregnant

Prenatal yoga is the perfect pregnancy exercise.

Not only can a yoga routine help you feel more relaxed and prepared for birth, but a once-a-week prenatal yoga session, when done for at least two months, is enough to reduce the risk of anxiety and depression. That, in turn, can lower the risk of premature birth and postpartum blues.

When you’re expecting, your immune system runs at a lower speed than usual — which is actually a good thing, since it keeps your growing baby protected and stops your body from fighting the fetus off as a foreign entity.

The downside: Your body can't ward off colds as well as it normally does, making you more vulnerable to the stuffy nose, cough and sore throat that accompany them.

If soap and water aren't available, use alcohol-based hand sanitizers.

You may have to wait until after you deliver your million-dollar baby to debut a new million-dollar smile. While there are no proven risks to tooth whitening, it's a procedure that definitely falls into the better-safe-than-sorry category and is best avoided while you’re pregnant.

Be sure to keep your teeth clean and well flossed, though. Gingivitis, or inflamed gums, is common in pregnant women, so keep your teeth healthy in between cleanings by chewing sugarless gum, which can help reduce plaque build-up, and snacking on nuts or cheese, which contain calcium and other nutrients.

Your super-sensitive gums will thank you for the attention, plus you'll increase your chances of having a healthier pregnancy. Believe it or not, poor dental care has been linked to premature birth. And isn't having a healthy mouth more important than having whiter pearly whites?

Vitamin C is essential for the production of collagen, which bolsters your baby's cartilage, muscles, blood vessels and bones. It also gives a baby's body the ability to repair wounded tissue.

And if that's not enough, adequate doses of vitamin C have been linked to a healthy birth weight and a decreased risk of premature rupture of the membranes. Since vitamin C can't be stored, you'll need to make sure you get enough servings daily.

You can get your C with the old standard — orange juice and oranges — as well as from a wide variety of delicious fruits, like mangoes, cantaloupe and strawberries, and veggies like red peppers, broccoli, collard greens and vegetable juice.

Dry skin? Taking too many baths can strip your skin of its moisture.

Stick to short showers — good training for actual motherhood — in warm, not hot, water, and use a mild cleanser. For very dry skin, try a moisturizer or put a warm-mist humidifier in your room.

What's the deal with your sex drive? Hormones hit every woman differently, turning up the heat for some and throwing ice water on others.

Pregnancy symptoms can also stand between you and a good time — after all, it's hard to feel sexy when you're busy gagging on dinner.

Rest assured, whatever's normal for you is normal. Remember that many women who've lost that lovin' feeling in the first trimester get it back in the second, in spades…so don't be surprised if a very warm front moves into the bedroom soon.

The nuchal translucency screening — also called the NT screening — is a specialized ultrasound performed between weeks 11 and 13 that screens for chromosomal conditions like Down syndrome, trisomy 18 and trisomy 13 by measuring the level of fluid at the base of the fetus' neck.

Because the NT screening only looks at the statistical likelihood of a chromosomal disorder and can't tell you anything definitive about your baby, it is usually done in conjunction with the quad screen or noninvasive prenatal testing (NIPT) to provide more comprehensive results.
