HELP!!! AFI levels!

Had an appt today. Im 34w6d baby is healthy and 5lbs3oz amd my belly is growing normally. The doctor told me my amniotic fluid is considered low... she said normL is 8 and im 7.7? Did any of you ladies go through this? Didnyou deliver healthy babies? Kind of freaked out. She told me to increase my water intake amd they will check my levels again next week... If they go up nothing to worry about. If not then i have to see a specialist😢
