Anyone consulted as private patient, please advice

Hi Mommies, I am 36 weeks and planning to change to a private patient. Does anyone know if I can still choose ward C as a private patient? My understanding was that if you are a citizen or PR you can go for ward C even if you are a private patient. Today someone told me once I go private I can only choose A or B1 ward. Please advise, next week is my first visit after that I will become private patient. I am not in a situation to go with A or B1 ward currently. If can’t choose ward C don’t want to go private.
