As far as I know po is kailangan atleast may 1year worth of contribution ka na or dapat nabayaran yung 9months na contribution before your EDD.
So kung ang EDD is Jan 2021, dapat nabayaran yung April-Dec 2020.
Pero mas okay parin po na mag ask sa Philhealth or kung saan ka manganganak kasi baka may exceptions sila ngayong pandemic.🙂
