No appetite, no nausea

Quick question? Not sure what to make of it. I’m currently pregnant with my 3rd baby. About 7 weeks along. And with my other 2 I was already experiencing some pretty aggressive morning sickness. This time around, I’ve rarely felt nauseous but I have absolutely no appetite, I don’t get hungry, and I don’t have any desire to eat, only drink. Has anyone else experienced this? I’ve looked up so much and all the answers about lack of appetite circulate about nausea and morning sickness which I don’t have yet. I’m super confused. The doctors haven’t scheduled my first appointment until I’m 10 weeks along.
