Irregular Contractions

Simran

I'm 37+3. Yesterday evening I had some mild period like cramping. Today morning I had contractions 6 mins apart then they stopped. I still have them once in a while but not that often, maybe once in an hour.

Are these true labour contractions or they are going to progress in labour contractions soon? How many days it might take for true labour to start? Anybody have similar experience?
