Contractions stopped?

So I had consistent contractions for around 8 hours, coming every 5-6 minutes lasting around 40seconds. Very mild but tightening like a wave and as it eased it went to my back and gave me back ache. I thought it was early labour and hopefully active labour would start soon. But they stopped about 2 hours ago. Is this normal? Has anyone had this and gone into labour soon?

Just want to add it definitely wasn’t braxton hicks. It made me have diarrhoea 3x (tmi sorry) and i drank water, changed position and went downstairs and it didn’t stop them.
