Discuss it with your hubby siguro mommy na you're planning to resign and pano magiging financial arrangement nyo if you do. If may savings kayong paghuhugutan na kayang macover hanggang sa delivery, that would be great. Pero if wala, kailangan nyo pag planuhan at pag-ipunan kung paano nyo ihahandle yung future expenses for check-ups, meds, labs, and delivery.
If hindi talaga kaya na mawalan ka ng work, try looking for remote work para at least sa bahay ka lang or discuss with your head sa current work if kaya nyo bang magkaron ng work from home arrangement.
