Making yourself throw up while pregnant!

I am 23 weeks pregnant & I started to notice that every time I eat I feel so uncomfortable after I am done. I feel like I'm so full when I only eat half of my lunch/dinner. It's to the point where if I bend over to pick something up from the floor I just want to throw up, even when I lay down on my bed makes my stomach hurt so bad, its to the point where I just have to make myself throw up to make my stomach feel better. Has any of you ladies felt like this during pregnancy? I told my doctor about it and she said not to worry.
