Abbreviations by default only work if they're exclusively made up of
"word chars" (a.k.a chars of syntax class "word").

So you can either change the char "." to be a word constituent (which
may lead to surprises), or you can change the setting on the
abbrev-table in which you placed that "p." abbreviation.

E.g. if it's added to the abbrev table named `foo-abbrev-table', you
could do

   (abbrev-table-put foo-abbrev-table
                     :regexp "\\<\\(\\w+\\.?\\)\\W*")

See C-h v define-abbrev-table to see the default value used for
the :regexp (to which I just added \\.?).
