Dark brown discharge soz tmi

Emmy

I’ve had some dark brown discharge since yesterday night on and off (I know gross sorry for the tmi) almost like old blood it’s such a small amount and only when I wipe, i don’t need a pad or anything and feel like I’m way overreacting. Not in any pain or anything. Had a scan two weeks ago everything was perfect. Just had a panic attack managed to calm myself. Just wondering what I should do? Contact EPU?
