Tokophobia, fear of childbirth, could I have it?

When I was 13-14, I was anorexic because I detested being fat & I managed to get over my disorder & maintain a stable weight. I am now 20 years old & still maintain a slim petite figure but when my fiance mentions us having a baby, I freak out because I am too afraid to have a baby form inside of me & suffer with the gross side effects & also the fact that I will be fat. Could this really count as having the fear of childbirth? Thanks.
