Do what feels fun.
If humor helps you feel more confident about it, go for it. If you’d rather keep it sweet and simple, that’s just as powerful.

Save the reactions.
Take photos or videos of people’s faces when they find out—it’s gold for memory-keeping.

Don’t overthink it.
This announcement doesn’t need to be Pinterest-perfect. It just needs to reflect your story.

Bonus Tip: If you’re not sure what kind of vibe you want, scroll your camera roll and find one photo where you both look like yourselves. Build your announcement around that.

FAQ: Unexpected Pregnancy Announcements

Sometimes the biggest question is: now what? Here are a few common questions answered.

When should I share the news?
There’s no right answer. Many wait until the second trimester, but if you’re excited now? Go for it.

What if people judge me?
That says more about them than you. Surround yourself with the people who support you. You don’t owe anyone an explanation beyond “We’re happy.”

Can I still have a shower or celebration?
Absolutely. Unexpected doesn’t mean uncelebrated. Celebrate your way—big party, small brunch, or just a cake with your people.

Bonus Tip: If you’re still feeling unsure, write a few drafts of your announcement in your notes app. You’ll know which one is right when you read it back and smile.

Not Expected—but Absolutely Worth It

You might not have expected this baby—but the love is real, the excitement is building, and the moment is yours.

So take the photo. Make the joke. Post the caption that says, “Didn’t see this coming.”

Because the best surprises? They’re the ones that turn into the sweetest stories.
