Bloody show????

I'm 40+2 weeks and I just went potty before I laid down for bed and I've had lots of pressure lots of trips to the bathroom with what feels like a full bladder and only a little comes out. As I went to wipe this last time a glob of mucus/snot with blood streaks in it was on my toilet paper. Is this my bloody show? And what does it mean as far as labor????? I have a pic just don't know if I should post it.
