What is this bug??

hey recently i discovered this odd bug near this small box where i used to keep many of my pets and plants things in (soil, fertilization gel, bird seeds, bird toys, etc). it looks almost exactly like a lady bug, but tiny and black with white spots. . I was freaked out a bit buit also curious of what it could be. and also, its starting to finally get warmer here and ive seen two earwigs and two centipedes and was wondering if any of these can go in my matress and on me a tnight. Yes i know i am bieng paranoid, but i cant stand the thought of them running around on me.
