Tight on cash and changing hospitals

I am currently in my 34th week, and I am supposed to be giving birth at TMC with Dr Jasmine. Because of this covid situation, i voluntarily took UPL because Im working at a hotel which is now currently a gov facility and there are positive cases. Because its voluntary, i dont get paid and i cant get help from gov. So now, i only could depend on my husband. We realise that we dont have enough for the hospital fees if i deliver there and thinking about changing to NUH. Has anyone ever done this? How is the procedure like? How do I request to change hospital? 😔
