Girls, I had this thing where my clavicle was hurting, now it's 29 weeks pregnant. Sometimes when I sit down I can't get up and go properly, at first I didn't pay attention, thought maybe I got stuck, but later such pains started and even with walking. It lasts about a week. Has anyone experienced something like that? What did you do in such cases?
