General Precautions

Wear Sunscreen
Being pregnant makes your skin more sensitive to sunlight, so you're more prone to sunburn and chloasma, those dark, blotchy spots that sometimes appear on the face. Apply a sunscreen with an SPF of 30 or higher (many brands now offer chemical-free formulas) and wear a hat and sunglasses. While no studies prove spending time in tanning beds can hurt your baby, the American Pregnancy Association recommends you avoid them while you're pregnant.

Stay Clean
Frequent hand washing can protect you from infections such as Group B streptococcus, Fifth disease, cytomegalovirus, and chickenpox, all of which can cause birth defects and other severe complications for your baby. Ethyl alcohol-based hand sanitizers are a great option for those times when you can't get to a sink. "They protect users from most of the communicable infections," says Anjan Chaudhury, M.D., an Ob-Gyn at St. Elizabeth's Medical Center in Boston.

Travel Smart
Go ahead: book that flight, but take some precautions. The Mayo Clinic say mid-pregnancy (14 to 28 weeks) is usually the best time to fly—by this time you're probably over morning sickness, and the risk of miscarriage or early delivery is low. Still, check with your doctor about any travel plans, and make sure the airline has no restrictions for pregnant women. On the plane, drink plenty of water to stay hydrated, and get up and walk around every half hour to reduce the risk of blood clots. An aisle seat will give you more room and make trips to the bathroom easier.
In the car, continue to wear a safety belt. According to the National Highway Traffic Safety Administration, the shoulder portion of the restraint should be positioned over the collar bone. The lap portion should be placed under the abdomen as low as possible on the hips and across the upper thighs, never above the abdomen. Also, pregnant women should sit as far from the air bag as possible.
