What do I need to know if I get into a car accident while pregnant?

Report to your doc. Regardless of the trimester you are in, you should inform your OB that you were involved in a car accident. He/she will have certain tests performed to ensure that you and your baby are safe. While driving or a passenger in any motor vehicle, a seatbelt should always be worn.
Get evaluation. After a car accident while pregnant, you should have your pregnancy evaluated -- immediately if you are having pain or bleeding.
