I Am 38 Weeks Pregnant Today And During My Biophysical

I am 38 weeks pregnant today and during my biophysical they found I have too much amniotic fluid. This is my fourth baby and I am meeting with maternal medicine tomorrow. I went from 18 last week to 28 this week. What can I expect tomorrow? Induction, c-section....does this mean my baby has problems? Should I be concerned about going into labor? I'm very nervous after reading online about it. Thank you.
