Changing OB

Hello po, I am currently 27 weeks pregnant po and due ko sa december na po. Ask ko lang is it okay pa po ba na mag change ng OB? Yung OB ko po right now is yung OB ko din po sa first born ko pero po kasi di ko na nagugustuhan how her new assistant treats her patients. Mag aask ka lang uli about something nakabusangot na and sobrang taray pa tono ng sagot. Unlike before ng dating assistant niya na super bait and talagang hands on sa patients ni doc.
