False labor ??

I'm a few days from 40 weeks and I haven't lost my plug but I had to be monitored yesterday for a little bit and they said I was having contractions every 5, 6, and 8 minutes but I didn't feel them at all. Today I've had a few but not close together and I'm having shooting pain down my left leg from my hip and it makes my leg feel numb. Could I be close to going into labor or could it all be false?
