Is very light pale yellow vaginal discharge normal? i'm 38 weeks pregnant and have very little pale yellow/white discharge. no foul odor, no itch.

So common: It's very very common to have increased discharge from the vagina toward the end of pregnancy. When i was pregnant, even though i was an ob/gyn myself, i was super surprised how much additional discharge there was. So long as you say, no itch, foul smell, then you're okay. I sometimes would wear a light panty liner, in this way you can see it, and try to ascertain... Discharge v. Water break. :-).
