SSS Maternity Benefit

Hi, mga mommies! I need clarification po about sa SSS and PhilHealth na din. December 2022 pa po kasi yung last na hulog ko since natanggal ako sa work ko before. Then freelancer or part-time lang work ko up to this date. My EDD will be in June 2024, 14 weeks preggy na po now. Nakita ko na between Jan-Dec 2023 daw dapat nakapaghulog ng at least 3 months sa SSS para maqualify sa matben. My question po is pwede pa po kaya namin habulin ung hulog, like magvo-voluntary hulog ako from October-December para mapuno namin yung 3 months na needed? Same scenario po sa PhilHealth.
