I have 2 questions

Braelyn • Baby #1 due June 1st
First, does anyone else get nauseous after they eat in the morning. I feel fine when I wake up and then after I eat I feel nauseous. I don't eat a lot either, I only had half a grilled cheese and not feeling too good. 
​Question 2: when did you start showing? I'm very very tiny, so I figured I start showing sooner, I'm right at 2 months and I see nothing. This is my first time being pregnant so I'm little nervous, I want everything to be okay.
