Pregnant post vsg need diet advice

I am about 18 months Post VSG and 14 weeks preggo. The first trimester was rough! Nauseated but felt like I needed to eat a lot to not feel nauseated and toooooo tired to exercise. I've aimed about 5lbs so far eek. I'm getting energy back so I will start exercising again but what should I be eating? I try to force the Protein shakes but eating meat and "normal" food seems to be getting more difficult. As pregnancy progresses towards the end has anyone had a difficult time eating normal foods? I imagine the pressure of baby on the stomach would make you eat less? My labs showed my protein is low and my Iron is high, idk ok he heck that happened and need to do better!
