So far, my biggest two complains are carpal tunnel and peeing all night long. I wake up with my right hand numb and both writsts are fairly sore during the day. Nausea would be on the list, too, but it ended at about 15 weeks, so it's not a concern anymore.
That's not all that bad, I don't think, since pregnancy is so often made out to be a nightmare :)
Things I love:
knowing the baby is coming soon!
looking at baby clothes
"Is it a girl or a boy?"
being so hard to turn over in bed
not being able to sit still very long
not being able to walk as fast
