My parents arrive tomorrow to stay with us for a week, including Christmas Day. They have no idea we are TTC and I have no idea if I am pg (tests BFN so far, AF due Christmas Eve). On the phone my parents have gone on and on about what wine they are bringing, and delicious cheese (you guessed it - Brie, blue cheese, unpasteurised Cheddar for some reason). Any advice on ways to gracefully keep them off the scent? I don't want to do anything to risk the baby if by some miracle I am pg, but I really don't want my parents to know as it may well never happen and I don't want to get their hopes up.
