okay girls what can it be

My period ended the 24th and today 26th I went pee and noticed some really really light pink when I wiped, it barely had any color to it. 
My urine didn't have any blood and my panties didn't have any sign of stain or anything. And I haven't had any sex.Could it just be some left over?
Ive gone pee a couple times today cause I've been drinking a lot of water and I've only noticed it 2x today and the rest of time it's been normal
