every pregnancy is different, but yes your hormones will be all over the place. I don't know if it will last the whole pregnancy or just the 1st trimester. I find that just saying something like "I know I'm cranky, I'm sorry but I can't help it" can be really helpful.

A great book for DH's is Dad's pregnant too!, by Harlen Cohen. I gave this to my DH with our 1st pregnancy and he found it very helpful. It doesn't turn them off like a lot of women's book do, and it's not patronising to men (which I find so many pregnancy books/advisors are) here's a link: Home

My DH signed up for the pregnancy tracker email newsletter last time - he said it was very useful. It can give them a great insight into what you're going through and what bub is doing.
