Does anyone get night sickness...??

Ke
Yesterday I found myself feeling pretty good and ate maybe 1-2 hrs before bed. 4 hrs after going to sleep I woke up feeling nauseous n my abdomen was throbbing. I couldn't get comfy or falls back asleep bc I got this crazy starving feeling.. So I got up and had three crackers n water n I was able to go back to sleep
 Does anyone else get this??? 
I'm only 5 weeks so I wasn't sure if this is early in the game to be "starving" lol 
Is it the hormones or what
