Decrease in vaginal discharge?

Melissa
I'm 37 weeks and 4 days. I keep reading on glow and in pregnancy books that the discharge is most likely heavier than before. Throughout my whole pregnancy I feel like I've had a lot of discharge and now for the last couple days nothing? Baby is still movin like normal and I've been having some Braxton hicks. But why the sudden decrease in discharge when there should be increase?
