Hi Sami
(again) lol Ive been having Braxton hicks since around 25 weeks and somedays I have loads and others I hardly have any. I have noticed the last few weeks them really getting stronger and stronger. When I was around the same stage as you I used to notice that if I did any exercise, then that is when they would start, especially if I walked up the road.
Sometimes now (dont know if anyone else has this) but if Brenty moves a huge move and obviously the head presses down then it will start one off
