Eh, that's usually the mucus plug starting to loosen lah, totally normal at 37 weeks! A few of my mum friends had the same thing, clear or whitish stringy mucus without blood or bad smell, and it just means your body is getting ready. Tapi kalau suddenly jadi heavy bleeding or constant flow macam period, or ada strong smell, then kena check dengan doctor jah to be safe. Otherwise relax jer, your body is doing what it should do, baby coming soon!
