What do contractions in your back feel like? I am concerned I am getting them. Had bad back pain for 2 days anyway and been feeling unwell but in the last hour I have started getting pains across lower bump but mostly in my back that are like sharp shooting pains from left to right side every minute or so but also have constant back ache underneath the shooting pains too if that makes sense plus I am having definite tightenings in belly too x
