Surprising hubby

This is advanced thinking but hopeful none the less. AF is due on the 17th. But Im hoping she doesn't come. We are closing on our first home on March 30th. Im looking for creative ways to announce to hubby incorporating the new home. Even if AF comes, there is another window of opportunity to still incorporate the new home and surprising DH. Im due to ovulate again at the end of the month on the 28th-29th. We aren't taking possession of our keys until April 10th. Hubby works out of town. So, we wouldn't actually move in until after I possibly get a positive test. Let the creative suggestions begin. And yes, I have been on Pinterest.
