Diva I can't answer your question about AND, I don't know anything about it really.
However, I'm generally quite a "glass half full" type person and being pregnant has gotten me down on many occasions. I think it would get anyone down.
If you believe all that's written about it in those godawful pregnancy magazines and books, you'd think you'd be blooming, staring down at your bump with whistful eyes and probably in soft focus. I certainly thought I'd thoroughly enjoy being pg and was surprised to find that actually, it's a bit of a pita.
If your dp thinks about it like this: if he had the following symptoms:
Tiredness, sickness, nausea, more tireness, exhaustion, feeling very emotional, needing more sleep but being unable to get it, high blood pressure, alternating with occasional low blood pressure so you feel faint, let's add a bit more exhaustion for good measure, and then breathlessness, oh and weight gain, weight gain until your body looks nothing like it did before, and much much more...
He'd be down at the hospital worrying that he had some kind of serious disease! Just because you are pg doesn't make all that any easier to deal with.
I hope someone on here can give you the info you need, but there is a thread you might want to point him in the direction of, that was posted on MN a few days back:
things no one ever tells you about being pg
It might make interesting reading.
Good luck, and > I'm sorry you're not feeling so good.
