First Time Mom

Hello everyone! I'm a first time mom at the age of 28. I'm currently on my 11th week now. I just wanna ask if its fine that I can't really sleep through the night.. everyday a sleep at 2 or 3 in the morning. I tried to sleep early but even though how much I wanted to sleep, It seems so hard for me to do it! and regarding with eating, as much as I wanted to eat for us to be healthy, I always throw up. I don't know what to do. please I need your advice!
