I think that's how it works here. To use a handicap spot legally, you either have to have a wheelchair symbol on your license plate (permanent disabilities) or either a sticker or a thing you hang from the rear view mirror. I don't know if pregnant women can get a temporarily thing or not, and it might vary from state to state, but I wouldn't have a problem with it.
