Anyone still not 100% convinced they are going to have a baby?

Hi all

I keep getting asked alot of questions about the future ("oh are you taking the baby on honeymoon?" Etc) and I never answer them of do half heartedly because I don't think I am going to get a baby.... I am trying to keep as positive as possible but I am so scared to think about the future in case something goes wrong..... Does anyone else feel like that? I don't even like thinking about the birth because Im convinced Im not going to get to that point. I feel like I am being negative, but I also want to do a bit of mental damage limitation I guess....
