With my dd i was the same from about 36 wks. The BH where timeable and reasonably consistent though did not increase in intensity or get any closer together but they would keep me awake at night and i was 4ever thinking is this it? I was eventually told i had an irritable uterus and it was some what pre labour. At 40 wks i had a stretch and sweep and was 3cm dialated but still had to be induced at 41+5! its not nice i know how you must be feeling but bub will come when ready.
With this pg i am having BH that wake me also and can be very uncomfortable but are not at all regular. I find a warm shower or heat pack etc can help me feel a bit better.
