Scared of giving birth?

I hear that you lose a lot of blood especially when you can't give normal birth and have to do cesarean section. I already get light headed, turn pale when needle is inserted in me or when they withdrawal blood. Can I faint during birth and what happens if that occurs? And there's a possibility that I can die? I'm really small but I'm not pregnant... yet. Just a curiously.
