Almost 10 weeks pregnant and my morning sickness is weird

So I'm eating well, including snacks and fruits. But for some reason whenever i vomit its only liquid at first but then follow up with actual food or sometimes its just liquid, as if there is liquid sitting on top of food in my stomach waiting to get out. I'm drinking water and soda but not that much! But there's excessive saliva all the time which apparently happens during first trimester. Is this normal? Cuz whenever i get rid of that liquid ( which isn't green or yellow its clear or cloudy) i feel much much better.

I'm waiting to discuss this with my midwife booking appointment in a couple of days, but any idea if this is normal?
