First pregnancy and scared to tell father and family

This is my first pregnancy and I’m super excited for my peanut ( my nickname for now). But me and the father aren’t together but he is my SL that I fell really deep for but I don’t know how he will take finding out that I’m pregnant. As well I grew up in a super religious household and though my older brother had my nephew 9 months ago I’m the oldest girl and I’m also now having a kid outta wedlock so I don’t know how to tell my mom… I know she will be happy after the initial disappointment but idk how to prepare myself for that conversation with either of them… please help!
