TMI Question....

I'm 5weeks 2days pregnant and am noticing a sweet smell from my vagina.... this is my 3rd pregnancy, but never noticed it before? Anyone experience this and have any ideas what it means? I don't go in for my 1st appt for another 4+wks. Nothing else going on down there but a mild amount of white discharge that I've been having this whole pregnancy. Any thoughts or opinions on it are welcome... thanks ladies!
