Weird symptoms!!!

So today i was suppose to start my period. After ttc all month! 
This morning i ate a sausage muffin and literally 1hr later i threw up, had super bad cramps and poop problems! It was terrible. & im not one to throw up at all. Later in the day i felt fatigue & nausea. I had no appetite later in the night. Right now im feeling bubbly feeling in my tummy. Idk whats going on?!?
