Need help ,please🙏🙏🙏

I miscarriage once last year..

And now I’m 30 weeks with a baby girl. Have been told everything is alright for the past 29 weeks. And went to check up yesterday, my Amniotic fluid is 8 and baby weight is 1.4kg. The dr said I’m low Amniotic fluid, baby is under weight and might be early born.

Is it low Amniotic fluid and under weight baby?
