My Hubbie made a comment last night about me not really having any Hardcore cravings and not being terribly over emotional, I got to thinking about that and couldn't remember for the life of me when those things came about during my last pregnancy (22 years ago). I've had foods that sound good, but nothing I would like take his right arm off for not having!
So when do those nice symptoms come about? I'm currently around 21 weeks.
Re: Cravings & Emotions
With my first, I wanted strawberry ice cream and french fries during the end of the first trimester (I think), but I gained far too much weight with that baby and am being more careful this time around. I was also very clam about things with no.1, which is not in my Type A personality.
I haven't really been craving anything with this one. But, I am crying more at stupid things, like sentimental movies and such. Not a total basket case, but definitely more flighty than with no. 1.
I never really had any major cravings or food aversions with this pregnancy (so far) or with my last one. DH does notice that I start to eat bagels when I'm pregnant.
I've always liked them guess I just eat them more often lol. I also don't think I've felt overly emotional either time. So maybe some of us just don't get those symptoms, at least not to the extent others do. I'd think that they would have kicked in by 21 weeks if they were going to. We should probably just count our lucky stars! 
No weird food cravings. I do go through periods where I will want to eat a certain food for several days in a row. For a few days it will be grilled cheese sandwiches....a few days later I will eat bowls of Frosted Flakes cereal for dinner each night.
My emotions have been a bit extreme during my 3rd trimester. I am not sure if it is completely hormonal or just a short fuse because of the general discomfort I feel all the time
