Brown blood but only when I wipe


I had my period recently, it ended last week so I know it's just leftover lining. I wore a pad last night thinking I'm starting again because I'm cramping too. This morning I checked my pad and it's completely clean. So whenever I wipe, there's remains of old period blood and I'm wondering how can I make the remains when I wipe stop?

Update: Just went to the bathroom and my pad has light blood.
