Do I need Multiple entry visa?

Hi Im Filipino I know we dont need one to travel to macau. But what if I entered macau via International Airport and that same they I depart straight to hongkong via the Turbojet? Of course I already out to Macau.
My question is Can I go back or can I still enter macau from hongkong on the next day to catch my flight from macau airport going back to manila? In that case do I need to get Multiple entry one? Btw Im going to macau on the 30th of april.
