One-sided contractions?

Delaney

Having regular contraction-type pain every 20 minutes but only on one side? Is this normal? Is this early labor? FTM and I can’t think of any other way to describe it other than a contraction. They last about 10 seconds every 20 minutes, but it’s only on one side. I’ve laid down and walked around and drank water but they’re still there. Is it early labor or just weird BH?
