Contractions 20 mins apart all day

Mildly painful contractions all day, 20 minutes a part. I had an NST this morning that picked up 3 contractions in 40 minutes. I seriously hope this progresses throughout the night! I'm so ready!! 39 weeks! This is the longest they have lasted without stopping. I seem to be on a contraction hamster wheel for a week! Start, stop, start, stop! Anyone else feel the pain!?!
