What does it mean when...

Christina • I have 3 wonderfully beautifully boys whom I love with all my heart.

Ok so my period ended on the 18th of March. On Thursday March the 26th at maybe about 6-7 pm I went to the restroom. I wipe and saw a dap or two of light red blood. What diu y'all think that is? Could I have scratched myself down there by accident? Give me your opinions please!!
