low amniotic fluid? 36 weeks

Ashlyn
I am 36 weeks today and o had an ultrasound at 34 weeks and my amniotic fluid levels were at 8.7. My midwife told me normal is between 5-25 but now after doing some research online it seems like a lot of people get monitored more closely with levels like mine. Anybody know anything about this? Other people were getting NSTs weekly or additional ultrasounds. Should I see a doctor and get another opinion?
