Yes. Same thing here. Your uterus is starting to push everything up into your chest cavity making you feel fuller faster. Be careful when you eat. I ate a bit too much dinner last week and ended up throwing up most of my meal.

I felt like such a glutton. *lol*
A good book to look into is "What to Expect When You're Expecting". That's where I read about everything being pushed up into your chest cavity.
Take care!
