Hi my back pain is when im sitting but also when im moving aboutMama1985 said:could i ask a quick question about back pain? was it constant? or was it just everyone time you stood up and started walking about? cos I have lower back pain and im about 5 weeks, and it only really hurts when im moving about? (if it isnt lol then its defintly the medication im on) dont worry im coming off it as soon as i can, they hospital already knows im pregnant
