Lightest pink when I wiped on tp

Li

14w4d and last night when I wiped I saw a very light pink spot on the tp I went to pee a few times after before bed and didn’t see anymore. This morning nothing either I’m just not sure if I should worry since that’s all the pink I saw and it was hardly anything but hoping it’s not the beginning of something bad. No cramping just sore body for the past weeks from everything growing I think. I am carrying twins btw
