Mucus plug or spotting (TMI Photos)!!

I was in Labor and Delivery last night they checked my cervix twice because I was progressing for a bit before contractions stopped. I know after getting checked it’s super normal to have some spotting. But I was just sitting on my yoga ball and my pants felt wet (no undies no they don’t fit) so I go to bathroom and check and it’s blood but it’s thick like mucus so I wipe and it’s like a clearish and pink mucus like when you blow your nose and it’s dry.

I’m a bit confused because with my first my mucus plus was pretty yellow and when bloody show came it was mucus with streaks of blood. So is this my mucus plug and bloody show, spotting, or should I call my OB and give a heads up?
