Does the possessive pronoun form of "it" have an apostrophe in it?

As a non-native English speaker it has always confused me whether the possessive form of "it" contains an apostrophe. I have seen both variants, but I'm not sure which one is correct.

Example sentence:
"The book had ink spilled all over its (it's?) pages."

No

Explanation:

To show possession, just use “its”.
The word WITH an apostrophe is the contraction of “it is”.
Just to point out, “it” is a strange word in the English language, and no other words follow this patter (that I am aware of). So don’t us PE this anywhere else!

I am a native English speaker and it confused me for years.

Explanation:

I finally realized that none of the possessive pronouns take the apostrophe.

she#" "# her (or hers)
it#" "" "#its
