I leaked for days before delivering, but I don't remember a particular odor. I was even unsure if it wasn't just incontinence. They checked me on the day I was due, but said there was no amniotic fluid. But when I went into labor four days later and it wasn't progressing, they decided to break my water. Ironically, there was none left.
So I was right that I had been leaking all along, even though the test didn't show it. (It was just a test paper that you, uh, moisten with the leakage. :blushing: But if you hadn't recently leaked, it wouldn't necessarily show.)
So if they do have you do that and it doesn't show up as amniotic fluid, see if you can take one with you to use when you notice the leaking.
But I'd definitely call and get yourself checked out, especially since you're so early.
