Nausea

Hi everybody 😊 I'm 7 weeks pregnant! But lately I've been feeling a lot of nausea even though I've never thrown up certain smells and especially after eating I experience a lot of it! So what calms it down is ginger ale. Before I became pregnant I never used to drink soda because of its sugar intake but right now all that calms down my nausea is ginger ale.. I only drink a can when its really bad .. And I try not to drink it everyday... Is this bad for my unborn baby? What do u guys suggest I do? Should I just stop drinking it because of the sugar? Thanks 😊
