Braxton hicks or real labour.

So This morning I lost a small amount of my plug. No big deal. Since 7am it's note 11 am (uk) I have had contractions about 4mins apart but not overly painful, enough to make me stand still until they pass. I'm 37 +5 but I've never gone into labour myself always been induced at 38weeks due to GD (that I don't have this time) I've had a bath that hasn't made a difference and also drank a fair amount of water to see if i was just not hydrated enough. Just don't know what to do with myself, is there anything you lovely ladies can suggest to encourage these contractions to progress or go away. I'm Very frustrated at the moment!
