Oh mama, I'm so deeply sorry for what you've been through, that's such a painful situation, at ang puso ko talaga ay kasama mo.
Regarding maternity leave, alam ko it can be confusing, pero honestly, kailangan mo talaga ng proper guidance dito because the circumstances are very special. I'd suggest reaching out directly to your HR or your DOLE office (Department of Labor) para ma-clarify kung gaano karaming days ang entitled ka, sometimes it depends on individual cases and company policy din.
A few of us mums have dealt with complicated leave situations, at nakita namin na ang best approach is to talk to the official people rather than guess, kasi baka mabigyan ka pa ng additional support o benefits na hindi mo alam.
For now, focus on your healing, mama. Take time to grieve and rest, your body and heart need it. Maraming hugs.
