When you turn down the food that you are craving because you simply have no more room in your stomach (even though you only had a very small child's portion) because you don't want to risk painful heartburn.
When you can only do number twos every three days and when the urge to go arrives, it is so intense that you hope that a toilet is close by because hanging on it is not an option.
When you look forward to being able to climb up stairs without your thighs hitting the under part of your pregnant belly.
And lastly when at the supermarket you give instructions to DH about which soft cheeses he is to bring to hospital the day after the baby is born because you just want to sink your teeth into the forbidden pregnancy foods so badly.
This is such a great thread ... it has made me laugh quite a number times because I can really really relate.
