Announcing pregnancy to dad and mom at the same time or separately?!

Hi,

I’ve just found out I’m pregnant and my boyfriend and I are absolutely over the moon. We’ve only known for two weeks ourselves. My boyfriend couldn’t wait to tell his parents, so we told them last week. But my parents still don’t know!!!! The reason we wanted to wait is because my dad is often away for work for longer periods, and we thought it would be nice to tell both of them at the same time. That meant I had to wait another week until he was back. Now it’s supposed to be 3 days until he’s actually home, but he just let me know it’ll be a week. I can barely hold it in anymore. My mom really wants to be a grandma, and keeping the secret is so hard!!!
I don’t know if I should tell my mom first (in a fun way, of course) and then my dad, or if I should still wait?

What would you do?

Best,
