Telling my family tomorrow

My husband and I are so excited and nervous because we are telling my family tomorrow and his family on Saturday! I am just scared something  will go wrong and I won't be pregnant anymore. I know the chances of miscarriage are under 1 percent for me now (I'm 12 and a half weeks) but I'm still nervous because I want it to be perfect. Which I wasn't such a nervous nelly haha wish me luck
