Hi cupcake
Sorry to read about your previous experience! I had to google Crompton Hospital, because I'm surprised about the staff neglect you mentioned. For a private hospital, that is definitely not on!
If you have had a previous c-section, you will be able to plan for another one at a Government hospital. They will not let you try a VBAC first, as it is seen as more risky. So you do not have to worry about that!
You should go to your local clinic for more information on what they need, they will also be able to refer you to the nearest hospital for scans and if there are any complications etc.
I am not familiar with Durban, hopefully someone else will able to help you more. I work at a government hospital, and giving birth at one is not that bad! Especially since it will cost you a lot less than R80k!
