Is anyone else really full only after eating a little bit?

Caitlin • Mommy to Mila Jean🎀

I’m 15 weeks pregnant and I can’t even eat half of what I normally ate before I was pregnant, I made chicken Alfredo for lunch today and could only eat maybe 6 bites before I was so uncomfortably full. Is this normal? What else could I be doing to help myself eat. I haven’t gained any weight either.
