OMG!! I stay hungry

I'm 6w & 2d pregnant & it seems like here lately on the days i don't have any nausea it's like I stay in the kitchen! I ate lunch & like an hour later my stomach was growling like I haven't ate all dang day. I can't help it.... Is anyone else going through this??? I don't want to gain a whole bunch of weight so if anyone also has some workouts I can do that's safe & healthy meals also that will help bunches... Thanks 😊
