Group Health insurance?

Sarah
Does anyone else have Group Health insurance? When I called them to ask about a breast pump they said I would be able to get one through insurance but I couldn't order it until after the baby was born. 
I talked to a lactation consultant recently and they said it would be best to have a breast pump earlier than that but 4 days after birth should be fine. I was wondering if anyone Who has group health was able to get a breast pump before the baby was born?
