Uy, mama, this is definitely something na kailangan i-discuss agad with your OB, hindi ako doctor pero low amniotic fluid levels need proper monitoring especially ngayon na malapit na ang due date mo. Don't worry, pero pls don't delay seeing your doctor kasi they need to check what's best for you and baby, sometimes they just want to keep close watch, sometimes may specific steps sila. Your closed cervix is actually good news (baby's still secure!), pero yung fluid levels combined need expert eyes, okay? A few of us moms have had similar situations and honestly, ang peace of mind from a proper check-up is worth it. Please see your OB this week if you haven't already, this isn't something to wait on. Keep safe, mama!
