Does this mean labour may be near or is it nothing?

It sounds to me like you are having back labor from the pains in your tailbone and lower back. I had horrible back labor and wasn't sure if I was in labor or not. The pain consisted for 4 days off and on and I went to the hospital 4 times before they finally told me I was in true labor bc I couldnt tell. I couldnt feel the labor pains in my uterus because they were so bad in my back. It sounds like you are getting ready to go into labor, time the back pains as you would regular contractions. Good Luck!
