Congrats, I also used 'What to expect when you're expecting', its a great reference book.
Its really annoying when people say 'we' are pregnant! Its YOU who is pregnant, but 'WE' are having a baby.

Congratulations OP but ...
He can be involved without having to be included in the "we are pregnant" thing. When he gets swollen ankles, haemmoroids, and pushes out an 8lb baby, he can be pregnant!!!!!
It's like the whole cutting the cord thing - men and women announce it as if it's a big deal! Cooking a meal, vacuuming occasionally, getting up at 2am to get the baby for feeding, walking up and down for hours if the little one has colic - THESE are a big deal!!
NOT coming on here in a year or two's time and bleating about how fat and tired your wife is and should you leave her for the local beauty at work is also a big deal!
