Probably Braxton Hix I've had them since six months I can tell they are contractions but I know it's too soon to have the baby 27 weeks 2nd baby (it's a girl)
If your almost 38 weeks and labor starts, your doctor probably won't even try to stop it. Just try to relax. The baby might have just dropped and is putting pressure on you.
It's probably not cramps, it's probably braxton hicks contractions
