Sweet smelling cm

Is it normal to have a really sweet smell to my discharge? Currently 27 weeks and idk if that's normal lol I'm also a FTM if you couldn't already tell lmao it's been like this for I'd say a week so I don't think it's a developing yeast infection. I also go for my glucose test on the 25th to check to diabetes but idk if the sweet cm smell is an indication of diabetes or if it's just a normal thing pregnant ladies have??
