Blood show or spotting from cervical check??

Ka

Not sure how to tell if there’s a difference? Dr said to expect spotting after my check this morning (7 hours ago). I’ve had blood in my discharge since then and it’s bright red or pink. It’s just mixed in with discharge though. I’m at 3cm over 50% effaced and baby’s head was way down on the sono (they were checking size) I’m 38+3. I’ve had some small contractions today.
