Strange smell (TMI)

So here's the "ewww, what's that all about?" post for the day. Over the last 1.5 to 2 weeks, I've noticed some "leakage" (I've been slacking off on my Kegels so I suspect it's urine) in my panties. However, it doesn't smell sweet (like they say amniotic fluid does) and it doesn't smell like urine - it smells strange, almost like popcorn but not quite(odd, I know). Guess I'll ask the doc about it tomorrow...
