TMI: Is this a bloody show or just the mucus plug?

M
Hi experienced mamas, is this the bloody show or the mucus plug?  I'm 4 days away from my due date and the bits of mucus plug I have been losing the past week are white or clear in color but this one looks a bit redder.  I hear that losing the mucus plug doesn't mean much but a bloody show means labor is near.  What do you think this is?  Thanks!
