Wasn't expecting what I saw at all

Wasn't expecting what I saw at all... Was supposed to start today and I'm normally right on time, I stopped to pick up a test and def wasn't expecting anything but the normal negative. Much to my surprise there it was!! POSITIVE! My heart instantly started rushing I ran to get my phone (after washing my hands) and called my boyfriend, he didn't believe me till I took a picture and sent it to him!!
