Anxiety about labor&delivery

I have this fear that something is going to happen to myself or my baby. I just can’t shake this feeling. I don’t have any fear about the pain that comes along with birth just that something could go wrong. Is this normal? How do I get over this? I’m 36 weeks pregnant and the closer I get to my due date the more my anxiety heightens. I just feel like me becoming a mommy is too good to be true and that I won’t get to actually experience being a mom because either something will happen to me or my baby. 😩
