Anyone have any idea ..... ?

I noticed that the little white moon shape is gone on some of them. And they look more of a white color, with even a purple color to them instead of pink?

Obviously my mind went a little crazy, and Google scared the crap out of me.

I went in for a Physical routine check about a month ago and did the blood tests they send you out for for routines? What could be the cause of this.

I just noticed or else I would have brought it up to doctor.

Plzzzzzzz any advice? They’re always like this 24/7

THX IN ADVANCE.
