Pregnancy is an amazing ride, but the morning sickness that often comes with it? Not so fab.

According to Dr. Marjorie Greenfield, ob-gyn and author of The Working Woman's Pregnancy Book, approximately 70 percent of women experience nausea early in pregnancy and about 50 percent experience vomiting. "It's very, very common, but it's also incredibly varied," Greenfield says. "Lots of people are sick all day, some are sick mostly in the evening, and others are sick if they haven't gotten enough sleep." Morning sickness can start as early as six weeks into pregnancy and tends to peak around the eighth and ninth weeks, according to Greenfield.

So how to deal? Check out the following tips. (And take heart: Many women find morning sickness symptoms taper off or disappear altogether after 12 to 14 weeks.)

Ditch Work

Having one of those mornings when the thought of dragging yourself out of bed for work is only compounding the nausea? Then don't do it! Take a sick day and give yourself a break. Your body's working overtime on growing that baby -- you deserve it.

Even better, Greenfield suggests scheduling a "vacation" during your seventh or eighth week, when morning sickness generally starts to peak. In either case, you won't have to divulge your pregnancy news to your coworkers before you're ready, and the time off will help you recoup, both physically and mentally.
