TMI Alert: Have I been loosing my mucous plug?

For the last couple of weeks now I have been having some discharge that is pastel yellow colored. Some times it is accompanied by reamy white discharge too. It isn't alot at a time and I only notice it maybe once a day. I will be 36 weeks tomorrow and everyone has been telling me that the baby is dropping. I haven't any that is pink or any bloody show, but I was just wandering if that was what that could be.
