December babies

my fiance and I recently found out we are expecting my first appointments May 7th if I did the math right my due date is December 26th this will be our second but I have a question I know an increase of appetite is expected but I am hungry all the time and I can never eat enough to get full it's to the point where it's almost hiring being hungry all the time I don't remember this with my first anyone else feel like this or is it something I should be worried about
