I have been experencing the same thing!! I have had some really strong and painful braxton hicks lately and have also noticed that I am feeling period like pain and lower back pain at times, especially at night and in the mornings without braxton hicks tightness. Don't know what it could be. Mine lasts a few minutes at times and then just disappears. Probably just the body getting ready for labour!!?? Not long to go, yay!!
