As title says......been getting pretty regular tightenings for 2 hours or so. Haven't been timing as haven't thought much of them but I'd guesstimate every 10 minutes or so, and they are now happening with a bit more discomfort than braxton hicks I've had previously. Don't know whether it is something or nothing 
. Difficult to judge by pain level as my last labour, the pain was very manageable right up to the end. I was very lucky!
I'm 38+2 and hoping this is at least body gearing up!
