Food aversions and not feeling satisfied

Chelsea
I'm 5w 3days and I'm not craving any foods but I usually (pre pregnancy) crave chocolate and sweet foods. Now I feel a little bit sick just thinking about them and don't feel like I want them at all. I haven't had morning sickness so far. 
I'm eating other foods like carrots almonds bananas etc as snacks and normal meat and vege meals for breakfast lunch and dinner. 
But I am feeling a little unsatisfied like I'm wanting something else but have no idea what it is...
Is anyone else having experiencing this?
