Nausea and vomiting may exist until around the 14th week of pregnancy. It may be worse in the morning, but unless it is excessive or interferes with adequate food retention, should not be cause for alarm.
Eating a few dry crackers before getting out of bed may decrease the nausea. A daily walk in the fresh air should help. Avoid strong odors and avoid rich, spicy, fatty and fried foods.
Eat multiple small snacks during the day rather than a few large meals and drink at least eight ounce glasses of water, milk or juice each day to stay hydrated.
