Hi mummy... you can ask for financial help assistance when you go for your checkups.
I just gave birth a week ago @ NUH and only paid for 2-3 bills which was the first scan which I needed to pay upfront and the rest was billed to my home address (standard procedure). The rest was paid via medisave (antenatal package which was included) when my husband registered for my admission. So don't worry ok! Have a healthy pregnancy ☺️
