Question...

My last pregnancy ended in emergency c-section.... and the loss of one of our twins. We are currently expecting again, due in May but I have HUGE anxieties about the repeat section. I am not allowed to give birth naturally due to complications last time (and not feeling labor this not knowing when I was in labor). What I am wondering is... can I request to be fully sedated again? To help with my ptsd, and anxieties surrounding birth? I have read and heard far too many horror stories about spinal blocks.... I have a really hard time wrapping my head around someone putting a needle into my spine.
