Drink Water

"Staying hydrated is huge," says Largeman-Roth. "It prevents constipation and it can prevent preterm contractions." The Institute of Medicine recommends that pregnant women drink 10 cups (2.4 liters) of water daily, which Largeman-Roth admits can be a struggle.

She recommends buying a pretty glass to keep at your desk, or, if you're driving around all day, a water bottle you really like. And make sure it is easy to clean. And if you find you're getting really bored with just water, add lemon, cucumber, or herbs such as mint or basil to make it more

appetizing. Teas, juices, and even fruits and vegetables can also help you get to your goal.
