I'm not sure if this is a sign of early labor but 3 hours into my shift at work today I got this lower back ache in the middle of my back and my tailbone which did not go away and it is now 7pm and I am having the back pain still laying down doesn't make it go away , standing makes it worse , a heating pad helps somewhat but I still ache , I thought it was just a backache from work and the babies position maybe but I only worked 5 hours I was off at 12pm ive been resting ever since so is it normal to cramp and have this back and tailbone pain all day that wasn't even there until 3 hours into my shift? I started cramping the other day all day then the next day it was back pain like this but not as bad and now today its been both all day and I am miserable
