Women who have had a C-section face a dilemma in their next pregnancy about whether to try for a vaginal birth, or to have a repeat section. Choosing a vaginal birth or a Caesarean section carries different risks and benefits but overall either choice is safe with only very small risks.n women who had a previous C-section, the risk of the womb rupturing during labour was seven times higher if they tried for a natural labour, compared with a planned C-section.
