telling my boyfriend!!

Hi all! 
     So short background: 
I was pregnant in November and miscarried at 5 weeks 4 days. Heartbroken and sad didn't plan on trying again any time soon. 
I was having the same symptoms I had before and just took a test and it was POSITIVE!!!! (Yay!) I suspect I'm 4 weekish anyway my boyfriend just went to go visit his sister in another state and left this morning but comes back Monday but I'd like to tell him a cute way when I pick him up from the airport. 
Any ideas or suggestions??!!?
