Pregnant or making myself crazy?? lol


i am 7 dpo and AF is due 10/13, but i just feel very different. i think im actually driving myself crazy thinking about this. i have been feeling super bloated, and i cant eat much without getting full very fast and getting heartburn. i have been having terrible hot flashes. i feel very nauseous. and ive been having bad cramping in my back and random jolts of pains in my abdomen. this TWW is going to kill me!!! any advice to help me stay sane????
