3 Weeks Pregnant

Toss some berries in your cereal. Adding vitamin C-laden foods to iron-rich fare increases your body's absorption of iron — a nutrient you need to help support your increased blood volume.

You can find vitamin C in fruits and vegetables like kiwis, mangoes, strawberries, melons, bell peppers, tomatoes and asparagus. Iron can be found in soy products, beef, poultry and dried fruit.

When it comes to hair coloring, experts agree that safe is better than sorry. So wait until your second trimester (i.e. after week 14 of pregnancy) before getting a touch-up.

When you do go back to the salon, stick to highlights instead of root lightening or root-to-tip color changes (this way, the chemicals won't touch your scalp) and request a gentler coloring option, like an ammonia-free base.

And be aware that hormonal changes can make your hair react differently, so you might not get exactly what you expect, even from your regular formula. Before you do your whole head, see about trying a test strand to be sure.

It's easier than you might think to find healthy options when you eat out or order takeout. If you're craving Italian, dine on grilled fish, chicken, veal or lean-beef entrees accompanied by gorgeous greens. Other good choices: pasta and pizza with fresh tomato sauce, pregnancy-safe seafood or cheese.

Enjoy teriyaki fish or chicken, miso soup, edamame and soba-noodle dishes from Japanese restaurants (as well as sushi featuring veggies or cooked fish). And, as long as your stomach's amenable to the spices, Indian restaurants make a particularly nutritious option — order practically anything that isn't fried.

In the past, you had to miss your period before you took a home pregnancy test (HPT) — then wait a couple of hours before learning the results.

These days, you can find out you're expecting much earlier, faster and with better accuracy than ever before (though accuracy will, of course, get better the closer you are to that missed period). So theoretically you could take one this early if you wanted to!

Still, it can take a week or more after you miss your period before you produce enough of the pregnancy hormone human chorionic gonadotropin (hCG) to be detected on a test. If you're late and negative, retest in a few days.

Calcium helps you and your developing baby build and maintain strong, healthy bones — plus it's essential for heart, nerve and muscle health. If you don’t consume enough calcium during pregnancy, your baby will take it from your bones!

Eat four daily servings (1,000 milligrams) of goodies like Greek or frozen yogurt, calcium-fortified juice or cereal and hard or pasteurized cheese.

If your morning sickness is accompanied by cramps, fever or diarrhea, you may be dealing with a stomach bug or food poisoning rather than pregnancy nausea.

But whether your stomach is churning from hormones, a virus or that egg salad you had for lunch, the treatment is the same: Rest up and focus on fluids — especially if you're losing them through vomiting or diarrhea.

Drink water, diluted juice (white grape is easiest on the tummy), clear broth, weak decaffeinated tea or hot water with lemon, which can lessen gas. If you can't manage to sip, suck on Popsicles.

Eat three servings of protein daily to help spur new tissue for your baby-to-be. One serving of meat like skinless chicken or lean beef, for example, should be about 3 ounces — roughly the size of a deck of cards. Other great protein sources include eggs, fish, dairy and legumes.
