Travelling close to due date?

Amber
My brother is about to ship off to basic, and his graduation will be during late August to early September, I'm not sure when yet. Anyways I'm due on the 12 of September, and I really wanted to go to his graduation. Would it be wise to travel out of state being so close to being due? Or should I just miss it? He doesn't want me to go because it's so close, but I've thought about surprising him.
