Full story: I was bbt'ing and my temps were staying up, so I told him I might be pregnant but could not be sure at the moment. We both left on a work trip on the day my period was about to be missed. I took the test.. a very light positive showed. Tested 2 days later. Line even darker! I have not told him yet. Before I left home i prepared a card with the first test saying "Hi Daddy!" For him to see when he got home, but I changed my mind and hid it in a drawer.

Should I tell him to look for the card with the light line, which might be confusing or wait to get home to hand him in person the darker line?

Ps. We had a miscarriage last year so I am still on a disbelief phase and thinking things can go wrong... that's why I also didn't call him immediately.
