sounds quite, quite awful and i can understand why you would be considering a section, it is so important to have faith in your care givers.
it might be worth looking at for a doula to support you before , during and after the birth.
and to ensure that you feel supported and that if you have concerns again, that she can speak up and be your advocate.
i would also be discussing oyur last birth with someone at the hospital, to put your fears of something being missed again, at rest. you can put in your birth plan about your fears and that would be perfectly reasonable.
you can also request a section if it looks as though an instrumental delivery would be necessary
you could also have an epidural , as a just in case measure, although that in itself can increase the need for an assisted delivery
i had my husbadn and best friend and my mum, who all knew how importnat a VB was to me, and knew how to support me.
if you have a gut feeling a section is better for you, then you might want to listen to that gut feeling
you might feel better ahving that control about it, but there are of course pros and cons to a section, it is not neccesarily an easier option in some ways, although you won't have the worry of a instrumental delviery
