You start digestion in your stomack

stomack
eat some ice it will setle you stomack
Your stomack growls because the inside of your stomack ist wavey and the bumps rub together when its empty because they do that to grind up food so when they rub together it makes a growling sound
Diarrhea is not a pregnancy symptom. it sounds like you just had a bit of a stomack flu. It always goes around at the start of every year.
Sit ups and pull ups are the best way.
sphincter
the acids in your stomack burn the food in to a solid and if you drink something like water, juice,etc it messes up the acids and it dont work right :)
