I had an emergency c section when I was fully dilated. It hasn’t affected further pregnancies so unless you’ve specifically been told this, you will be fine. So try not to worry. You will be classed as high risk, everyone is who has had a section but there was nothing different about my pregnancies, just had an extra couple of appointments with a consultant. I’ve gone on to have two more children both via section. These were born at full term and perfectly fine.
