Having twins

A couple is trying to have a baby. Finally, the blonde tells her husband,
“Honey, I have great news! We’re pregnant, and we’re having twins!”
The husband is overjoyed and says to his wife, “Honey that’s wonderful, but how do you know so soon that we’re having twins?”
She nods her head and says, “Well, I bought the twin pack pregnancy test and they both came out positive!”

Anything?!
