Huge appetite?

I'm 40 weeks pregnant and my appetite for the past two weeks has just become huge. I've always been a regular eater,breakfast then a snack then lunch dinner and a snack again. But now there is nothing that's stopping me from being hungry, so far I've had my breakfast and lunch pineapple orange yogurt crisps and a chocolate bar,and I'm still hungry! Is there any tips on how to suppress this? It's just ridiculous now.
