All depends on how much of an emergency and your personal experience, how deep they cut, etc. I had an elcs due to iugr. They told me it takes two years for a woman to recover from a pregnancy. I was advised to wait at least a year, preferably 18 months if I wanted a vbac and a safer pregnancy. I did get pregnant 7/8 months after losing Joshua, but mine wasn't an emergency and very standard, and had healed ok. Best to speak to your dr/consultant for their opinion.
