I have put on about the same as you as well.. and the laast couple of weeks I have been living off watermelon, can't get enough of it!
I ask my Dr at every weigh in if the amount I have put on is ok and he always says it's perfectly natural to put on a few Kg's... he doesn't seem too concerned. So, enjoy the last 3 months you have of being able to eat whatever you fancy, I say, just keep it on moderation
