Every time someone asks and I tell them, "yes, I'm still working full time", they look/sound horrified at the thought!! I'm planning on going off one full month before my due date but until then, full time it is. There are days when it certainly sucks big time (and the first trimester was very challenging), but its not THAT bad.
ETA: I am a teacher, so mostly on my feet all day.
Did you work full-time throughout your pregnancy?
