Help help help

I'm 19 and this is my first baby.  I have so many questions can someone help? When will I start showing? Or when do ladies begin to show. What are your views on water births and do epidurals hurt as bad as I think they do? Am I gonna be effected in my sleep the entire time because my sleeping already has changed😅 Sorry for my over flow but if you can't tell I'm freaking out. Please and thank you😩
