Thrush??

[doulamamma]

Thrush is very itchy on the lips and inner of the vagina - and is white discharge with redness on the skin - it has an almost sweet smell. it sounds like you have normal 3rd tri discharge and probably not thrush, but if you real concerned see your health care professional.
good luck

Don't know if this will help but it's a kind of yeasty smell.
