How do I tell Daddy?!

Brea

Just took a test this morning and it's positive!! OMG I had to take the day off I couldn't stop crying for joy! We were supposed to go to Chicago this weekend for his birthday but I don't want to wait. If I'm not drinking, he'll know and he may not want to go at all! So what's a cute way to tell him? I don't want our two school aged kids knowing yet, not until we talk to a doctor. The older two are mine, this is his first! I thought I had this but I don't know what to do, I can't focus...

Help ladies!
