Random bleeding?

24 hours ago I noticed bleeding when I wiped after going to the bathroom. It was more than spotting but wasn't heavy enough to go through to my underwear, so I thought it must have been my period starting. However, it's been 24 hours now and I've had no other bleeding and nothing when I wipe. So I'm a bit confused. Does anybody have any advice or ideas of what this could be? Of if it's even normal? Could it be implantation? Or just a very very short period?

*I don't have any photos because I thought it was the start of my period. Also I don't know when I ovulated this month as I haven't been tracking due to the business of Christmas coming up.
