Buy a baby bottle and out the test in it and leave it where he will see it
With our first, DH was helping a mate move. I got there before he did, and as he walked through the door, I said "hello daddy". He let a few choice words go, so I showed him the test to prove it
The rest i have just blurted it out "I'm pregnant". Nothing creative lol.
