Not sure what's going on with my appetite...advice?

I'm 13wks and 1 day. My nausea has mostly worn off and I'm trying to break away from just eating snacks all day. I need to eat actual lunches and dinners. I struggle with meat still. I'm trying to be more nutritious and healthy now. I've noticed I'll try eating a meal (meat or not) and I have a wierd sensation of I'm full but still hungry. I notice it more with protein heavy meals. But even if I'm eating pasta. Its wierd and idk how to get past it or what to do. Anyone else have this problem?
