Akak tak sure exactly mana ada dekat Johor/Melaka, tapi usually government clinics (klinik kesihatan) dekat area you boleh tanya, a few of my mum friends dari Melaka cakap their nearest clinic ada antenatal classes, usually free or murah jer. Best way is call your nearest clinic or hospital maternity ward and ask, sebab timing and classes dekat each place lain-lain. KKM website might have info jugak!
