I am feeling blessed because today is my full term pregnancy with my second child. My first child I had her natural, I plan to do the same for baby #2. My first child is 10 years old, I wasn't have no pain nothing during all pregnancy. My second one I have now since yesterday I had a bad back pain I wonder if might be a  sign for labor or contraction I don't know. I stop working , stop driving until my water comes for labor. I am home doing my excercis, eat healthy, drunk a lot of water, get rest.
