labor? or false alarm?

Currently 34+4 and yesterday i was walking all day literally since i went out shopping, but had to come home cause i was starting to get braxton hicks but as soon as i got home the pain got worse especially on my back and doesnt want to leave, i have been trying to lay down, walk, take a bath, etc but nothing seems to work!! This is my 3rd pregnancy, my previous ones were never like this so im so confused! 😫
