Not afraid of birth?

Ok is there something wrong with me? I keep seeing countless posts of people being absolutely afraid of giving birth. I have 0 fear around this and I'm starting to think something is wrong with me. I also haven't had many emotional moments about being pregnant, I hear women describe crying and being overwhelmed with love and emotion over ultrasounds and kicks and I just don't feel any of this. Like I am excited and this was very much planned for but I'm worried I'm lacking some maternal instinct or something..
