That's normal, it will come and go your whole pregnancy, try eating healthier snacks!
I am constantly snacking, 12 weeks 2mro. And I'm loosing weight lol. But my tummy is out there already. I think as long as you aren't putting on too much weight you are fine.
I'm 10 weeks 5 days and I am exactly the same way. Usually I eat 3 normal meals and snack on fruits and veggies throughout the day.
