I'm 26w pregnant with my 3rd baby. The 1st I laboured for 3 days and only dilated 3cm then had an emergency section and the 2nd I had a planned section. I don't remember ever getting these tighenings in my previous pregnancies. This time my stomach tightens and goes hard quite regularly. Do you think this is a good sign that my body is getting ready for labour? I've always been a bit worried that after 2 sections my body won't know what to do.
