Hi Jodie
Similar thing happened to me, I found week one easy and didn't feel hungry but week 2 killed me!!!!! Was hungry permanently and I swear it was real.. my stomach never stopped rumbling.. took every ounce of willpower not to cheat.. that was also the week I sought the internet for help and found minimins!
Even now I still have the odd day when my stomach rumbles and I feel hungry, not a clue what sets it off, CDC says it isn't possible when in Ketosis, and I have never come out of Ketosis. As cheekymare says, keep yourself occupied.. the feeling does go away if your mind is busy... Going out for a coffee helped me whenever I was feeling peckish!
good luck
