TMI Pic = Mucus Plug?

Hi all, I’m 36w3d and per my OBYN at my appointment at 36w1d I was already at 1cm dialated. First time mom. Anyway, is this my mucus plug or just extra discharge? It is a little “hard to go” if you know what I mean, so I was straining a bit. And since she checked my cervix and to ensure baby is breeched properly, that could just be dry blood from that?
