My bubs is very active during the night wakes me a LOT!~!! My tummy aches from all the movements, which is really distressing.
I can tell you with DD3 she was very busy leading up to and during labour which I thought was strange, I always thought they got quiet, but apparently not so. I reckon it sounds like you may go into labour soon, and bubs knows it and is getting hyped up with the extra hormones, hence the differnt bowel movements.
