should i be worried ? please respond!

i found this little thing sticking out of my cat. i think it’s a skin tag but i’m not sure. i also think i bursted it cause black liquid kind of stuff was coming out of it as you can see in the first picture. the second picture was before it came out. it’s incredibly tiny too!

my cat doesn’t show any sign of discomfort or anything at all even when i touch it so i’m hoping it’s just a skin tag.
