Yellow skin, pale stool?

I am on Vitamin B12 as well as Vitamin D supplements after being diagnosed with low levels of the two.
However, I frequently tend to forget my Vitamin B12 medication.

Recently a couple of colleagues of mine noted my skin yellowing.

At the same time, I myself, and many others do not notice any such coloring, yet, I am afraid I have some condition that causes jaundice.

Despite that my eyes themselves are not yellow although I do have some red lines about my sclera (always have though, likely due to lack of sleep).

I fear this yellowing might be related to a liver problem since my stool was, for the past two days when I checked, pale in color.

Despite that, I am not experiencing any pain nor is my urine darker.

Is my slightly yellow skin just a result of a B12 deficiency and my pale stool a random condition that will pass?
Does stool often change colors without cause for concern?
