Low amniotic fluid and small abdominal circumference at 28+2weeks

Went for growth scan and my amniotic fluid is low, at 8.1cm, baby's abdominal circumference is measuring small in the 7th percentile and fetal weight is 1043g at 12th percentile. My dr said it could be due to underlying placenta issues and may have to induce at 37 weeks if that's the case and wants to do a rescan in a week to monitor. Any moms have advice or experience on this? Any ways to increase amniotic fluid and increase abdominal circumference? #firsttimemom
