Im 34 Weeks Pregnant And Am Having A Lot Of

Im 34 weeks pregnant and am having a lot of discharge. It is white and yellowish chunky discharge. No odor or itch. I went into pre term labor Oct 23 (27 hours of painful labor) they stopped it. They also tested me for early labor and it came back positive. Am I losing my mucus plug? I've been having a few painful contractions here and there also, nothing to call my Dr about though.
