clumsy and emotional

La
Ok I've just about had it with this darn day. 
I have dropped my plate of food this morning and again tonight spilling half my food both times. 
And when I was in the middle of getting my hubby food together and he told me to sit down and relax because I was doing to much. Crazy Thing is I wasn't doing anymore than I always do for him. And when he told me that I began to cry. I mean I'm fighting tears as I write this entry. 
Is this normal?  Anyone else super emotional and/or clumsy. 
Oh and BTW, I'm 31w today!
