Uy, mama, I know this is scary, pero please go to your OB agad or go to the hospital if kailangan mo ng immediate check, ha? Low amniotic fluid is something na kailangan ng doctor's proper monitoring at guidance, hindi ako makakatulong dito with just advice.
Your OB will know best what to do next based on your scans and how far along you are, they're the expert dito, not us moms sa forum, hehe! Maraming cases ng ganito na naging okay dahil sa tamang medical care, so don't lose hope, but please get professional help ASAP. Sending you so much love, you've got this.
