TMI - Bloody show or mucus plug?

Currently 38+1

So yesterday at about midnight I woke up to lots of pink dischargey mucous. Went on all throughout the night, and it’s now 3 in the afternoon and it’s turned more brown.

Is this my mucus plug coming out or bloody show?? It feels like a lot to be just the mucus plug.. hopeful that baby comes soon! Lots of “pressure” really low in the abdomen but not often. Maybe once an hour or so? The attached pic is of me changing my liner for the 4th time, and it wasn’t as heavy as the first 3 times.

Baby is kicking tons so I know s/he is doing ok
