Private Part Oder?????

So I noticed for the past three days there is a oder coming from my female area. It's not a smelly oder nor does it itch it actually smells sweet which is weird bc I don't use smell good products down there ever since I got pregnant. The first couple times I thought it was all in my head but I'm realizing it's definitely not. Has this happen to anyone else....I'm a FTM so i don't know all the changes that happen to your body especially down in that area, this is all new to me.
