Maternity Leave

Help mommies! First time mom here. Due date ko po is November 23, 2019. Currently I'm in Luzon coz my work is here. My mom wants me to give birth sa province po. But my doc said gang 28 weeks lng sya nagbibigay ng fit certificate for travel. Yung airlines nman po is nag aallowed hanggang 32-35 weeks mag travel. Problem ko po is yung maternity leave which is 105 days more or less 3 months. So until 7 months lng ako pwede mag travel. After counting, right after ng birth ko saglit ko lang makakasama si baby kasi need bumalik sa work. Are there any chances na pwede mag extend yung leave po para makasama pa si baby? Any working moms here po? Need ur help ? wala po kasi magbabantay kung dito po ako sa luzon manganganak. Hubby nman po is malayo din ang work at pagod araw araw sa byahe. Ayaw din naman po namin kumuha ng yaya na hindi kakilala. Thank you po sa sasagot.
