I have had 2 boys, the first one by forceps delivery and the second by emegency c-section. Both times the labour has progressed normally until 5cm dilation at which point suddenly I have needed to start pushing and the babies heart rates have dropped dramatically. This has made the last 5cm dilation happen within minutes. As I am pregnant again my obstetrician has agreed to a trial of labour, but warned me to be prepared for another c-section just in case. I am wondering if I would be better or worse off if I have an epidural during the labour, or would this make it harder for me to deliver vaginally?
