Is ginger candy bad?

So I've been sucking on ginger drops for about a week now. Now I'm starting to wonder if I'm sucking on pure sugar😱 I was told the ginger candy was good for the nasua so I just started sucking on them like no tomorrow. Now I'm nervous that I'm just sucking on pure sugar😫 3rd pregnancy and I'm 34 now. I don't want to be hit with diabetes or any of them bad things. Being pregnant in your 20s is not as smooth in your mid 30s😪😪😪 just my personal opinion and experience.
