Ayyy, napakahirap ng situation mo, sending you a hug. Based sa naiintindihan ko, the SSS should still approve it since you filed MAT1 before the miscarriage happened on the same day, yung filing date ang magiging basis nila, hindi yung actual status ng pregnancy pagka-file mo. A few of us moms have gone through similar timings with SSS claims, and as long as you had a confirmed pregnancy with medical records (which you do, from your ultrasounds), they usually honor it, pero I'd really suggest you follow up directly with your SSS branch or call their hotline to confirm your specific case kasi bawat situation ay slightly different, better safe than sorry, especially ngayon na emotional and physical recovery mo na talaga. Wishing you well, momsh.
