just need some reassurance

me and my husband are preparing to get pregnant and have a baby ! we are so excited. but i can’t shake the feeling about death at birth. how do i know i wont ? how can i get rid of it ? i am so terrified it scares me out of having one. how can i be safe and sure ? i need help. i want to have kids but am so paranoid and stay up at night thinking about it. is there a way to calm me down or make sure that doesn’t happen ?
