Do i need maternity insurance when I already have health insurance?

Just found out we were expecting... I am using Aetna health insurance, Do I need to add maternity insurance? Does it make a difference?

if your policy doesnt cover maternity then yes you need maternity insurance. regular insurance wont cover and maternity costs. if you are pregnant but dont have maternity coverage through aetna already, they wont give it to you now that you know you are pregnant.
