Sweet smelling vagina?

Ok ok I hate to be this person but being almost 3 weeks late and no sign of period I'm asking. Today out of no where I notice my vagina smells very sweet.. super tmi I know. But I think I remember something about that when I was pregnant with my son? I honestly can't remember so I'm asking you ladies in the first trimester to help me refresh my memory, did you notice a different smell early on?
