It seems to make my intermittent pre-labour contractions more painful so I stopped taking it, I will start again in a few weeks but couldn't bear the thought of having more pain for all those weeks. I took it with DS#2 and had a long prelabour and 2 hour (probably less) labour with bubs arriving ten minutes after I arrived at the birth centre. Right now I am having an attack of prelabour so the thought of taking it isn't appealling for me!
