So Leukorrhea, eh?

Mi
Due date is fast approaching & yesterday this discharge started that gave me a head scratch. This is my 3rd & I do not remember this from my first two. So I call my midwife like "uhhh, what's this white liquidy non-sense?" I've had yeast infections, this was just coming out with no end in sight yet no other side effects. She told me it's leukorrhea, basically white blood cells released from hormones which signals your due date is near. She assured me it is normal & asked when my next appointment is, (Monday) then said "well, if you make it to then, we will see you Monday!" (I feel like you shouldn't say this to a 39+2 week pregnant chick, but ok.)
My question is: is this a sign that labor MIGHT be near? I can't imagine this continuing for 3 more weeks but, hey, pregnancy isn't exactly super cozy thus far. Anyone have any insight?
