Philhealth

Hello mommies. For those na may alam I just want to ask about my Philhealth. I was paying my Philhealth since March 2017 to Dec 2019 since employed ako. Then by Jan 2020 hindi na since nagstop na ako ng work. My due date is on June 14 2020. Do I have to pay from Jan-June para eligible parin sa Philhealth? or Jan-March payment lang qualified parin ako? Thanks in advance....
