Inversion ?!

Tayste
Has anyone had one and can give me their experience? My baby is breech so I'm scheduled for one tomorrow. They said that they're going to give me a spinal and probably and epidural too so that I'm completely numb and the epidural for the chance that I end up needing a c section. They said they would only do the c section if something goes wrong with the baby, like his heart rate drops or the placenta detaches. Has anyone had anything like this happen? I'm really nervous something is going to go wrong, I'm no where near ready for baby to arrive! I just need to hear other stories 😅
