Is this my mucus plug? Should I be worried?

So on Thursday and Friday I lost some of my mucus plug but it was clear/yellow so I knew it was my mucus plug. It was only a tiny bit each day. I just woke up and went pee this morning and a bunch of chunky pink stuff came out? There was a big chunk at the bottom and then little chunks. I’m now spotting a bit and cramping. Would this maybe be the rest of my mucus plug? Are they even supposed to be pink? I’m so worried. I’m only 35 weeks today and I don’t want to go into labour yet. Here’s a pic of some of the stuff. And also no, I don’t have an yeast infection or any infection I was just cleared about that a couple days ago.

Sorry bout the pee btw my anemia pills make it very yellow
