Not hungry anymore 😕

I'm 30 weeks as of yesterday, but I noticed that I'm literally not hungry almost ever. I drink plenty of water, but when it comes to food, I'm just not interested. the craving have completely and smells make me puke again like in my first trimester. But even then I was eating at least two meals a day. My second trimester I was hungry alllll the time, I would constantly be snacking and have all three meals a day. Any other moms have this? What should I do to help? I feel like my princess might not be getting everything she needs anymore :(
