Pink Spotting after period

My period started Dec 26 & ended Dec 30. Today I noticed some pink in the cm. Is it normal for that to happen after a period? I've never saw that before in any of my periods. This morning my cm was sticky & when it was pink the cm wasn't sticky or watery cause I tried to pull it apart & there wasn't enough cm to try it. Even though Glow says to bd today I just don't see any cm that points in that direction.
