Signs that my body is "acting" pregnant

besides the obvious growing belly...

1. my lower back is aching. started yoga again and that seems to help temporarily
2. ran into 2 different walls today
3. missed my mouth and dripped salsa all over my shirt. seriously, getting food from my hand to my mouth is becoming increasingly difficult
4. can't seem to remember anything without writing it down
5. craving chocolate at least twice a day

ok, maybe that last one has nothing to do with being pregnant, but still...
