Leaking vagina?

Shelby
The last few days I have noticed that my vagina, and pretty much everything downstairs) has been wet CONSTANTLY. It doesn't matter if I have just gone to the bathroom and wiped REALLY well, within 30 minutes I will be moist again. The fluid is clear and oderless, but constantly being wet downstairs isn't a good thing. What could this be? 30 weeks and a 3 days.
