The secret is killing me!!

I am incredibly impatient and not a very good secret keeper. I found out I was pregnant on Saturday and obviously told DH but I want to tell my parents in person and they live 4 hours away so were going up to see them this weekend. Then once we've told my parents, we'll come home and tell my inlaws. I don't plan on telling anyone else (except maybe our sisters) until I make it to my 2nd trimester. But it's only been 2 1/2 days and I swear I feel like I'm gunna explode! I HATE not being able to tell anyone! Especially talking to my mom on the phone everyday and not telling her!! I feel like I'm going insane! How do you all handle keeping your early pregnancies a secret?!
