Should I get a navel piercing?

I leaving in a few days to go on a vacations overseas. I really want to get it done. I just don't know if it would be better to get it done when I get back in a month. Do you think i should get my navel pierced? How likely would it be that it would get infected cause that is what i am really worried about? As of now i already have an appointment booked but i don't know if i should call back and reschedule. I really need an honest opinion...
