Pre-labor symptoms

Michele
Anyone else starting to feel different/ "off" or have any prelabor symptoms?
The last week: 
hot flashes on and off, baby dropped, increased pressure is an understatement, awake every 30 minutes
Last couple days: 
NESTING, NESTING, NESTING but then crazy exhausted, better sleep, pelvic & rectal pressure/vagina pain
Last night: 
SEVERE diarrhea, chills, hot flashes
This morning and today: 
Crazy "burning-type" cramping in entire stomach, dull low back pain but fairly constant, NO APPETITE! Felt I had to get my hospital bag ready before I could leave for work cause I had a weird feeling. 
I'd love to hear how all of you are doing!!
