38w, reduced movement NST and now a BPP ultrasound

Hi ladies!
FTM, 38+1 I came in for my regular checkup and noted my decreased fetal movement from last night and this morning... so they did an NST and my little boy wasn't really cooperating.
They said I'm 2cm dilated and 80% effaced, but I know that doesn't tell us much until I'm in labor. I've had inconsistent contractions and cramping the last couple days.
So now I'm waiting for my appointment in an hour to have a BPP ultrasound to check fluids.
Have any other mamas gone through this? What was the result? Did they induce labor? Any insight is so appreciated, I've never been here before!
