Argh! I'm becoming Irrational Pregnant Woman!!
*giggles* We need to get you a cape and spandex suit with a big "I" on the belly! You can dash from house to house and become irrationally upset - making men appreciate their PMSing partners once and for all! A true hero!

Honestly though - Wish I could make it better - but if your brain is saying you need to cry, then just do it. I am sure they all appreciate, despite the fact that they are trying to make it easy for you, that this is NOT going to plan at all.
