Appetite

Ok so I am 26+5 week and my appetite has increased a lot, I find myself hungry at the most random times, I'm alittle hungry in the am and eat something small at lunch but then in the evening I'm super hungry and sometimes at 4am I wake up hungry. Does anyone else have this going in or had this happen? It not like I'm eating alit of junk foods I mainly snack on fruit or a bowl of cereal, and I'm not sure if it's good or bad, and most often weight gain has been in the last month and a half.
