KKH appointment - 3rd trim

Hi all, Im currently 29 weeks, still under kkh subsidized. My next appointment will be on my 32nd week. (Still under subsidized) However i recently enquired KKH, to change me to private gynae (gynae of my choice) on my 35th week. And the next available date of the gynae is on my 35th week. Usually i hear people’s appointment after the 32nd week is 36 weeks but hardly heard their appt on 35th week. Is it too early of interval ? Should i reschedule to my 36th week instead ? #ftm
