37 weeks help

Court

Just left the dr office I’m not dilated but starting to thin out he said a couple more weeks for sure he said to Stay off my feet from bc I’m retaining fluid. I just went to the bathroom and had this when I wiped. It’s looks like it would be my mucus plug/ bloody show but at 9:10 this morning I wasn’t dilated so how could that be?! Any suggestions as to what this is or if you’ve experienced this would be greatly appreciated!!
