Wow. I thought I was kind of bad, but I guess not really!
I cried mostly at songs and ads. The OnStar ad that was going on when I was pg with DD2 was bad for me - lady gets in an accident and calls onstar and the onstar guy calls her husband for her, and an ambulance.... (real life call, but honestly, not worth tears!)
I have a favourite CD that my brother made up for me. When I was pregnant with DD3, EVERY SONG, even the funny ones, made me cry.
The only other thing that made me cry was being exhausted and trying to get supper ready, but that's not anything really weird, I don't think. That can happen pg or not!
