This is my 4th I really should no the answer! The shows I've had before have been more 'slimey' (apologies for the description).
I've been wearing a pad as I've got a cough and I don't trust my bladder and today I've noticed a patch of brown on it.
I've also been getting lots of twinges really low down (cervix maybe) - right down low not around my stomach.
Does it sound like a show? A little bit of blood is ok isn't it? And it's not bright red or anything.
