Hiccups

I'm currently 39 weeks expecting a scheduled c-section June 20th I just had a question should I be worried if unborn baby has hiccups a lot ? Its maybe once or twice every day for about 5 minutes then he tends to get over them .. ? Is that a good or bad sign ? I asked my Dr. but he seemed to just ignore my question or he was in a bit of a rush I live in a small town .. Any help would be appreciated !
