Getting ready

So Friday me and my boyfriend is going to try for a baby!! And he's confident that we are I want to have a baby but I'm afraid of what my mother will say and will she be there for me throughout the whole thing (probably not) he said his parents will be ok with it but I don't believe him. I need tips on how to prepare myself for getting pregnant, what to do when I am pregnant and how am I gonna break it to my mom (I'm gonna tell her the truth and nothing but the truth why I'm pregnant) and how I'm gonna support it after its born so who ever responds thank you very much for your response
