TMI: I think I lost or am losing my mucus plug?

For the pass few days I’ve been getting A LOT of discharge & it just gushes out (tmi) but this morning it was a whole lot mire & it was very clumpy, yellowish white. It was like i queefed (no control) & it gushed out. & afterwards I had some pressure & period like cramps for a bit but went away. I am 35 weeks pregnant today.
