I can't believe it!

My husband and I have just been casually ttc for the summer. It's been incredibly hard since we have been living with my parents for the summer while we aren't in college. My af was supposed to come yesterday, but it being a little off is never abnormal. I am sitting at work, and I had a pregnancy test in my purse and decided to take it just so it would show me a negative so I wouldn't have to worry (wasteful I know but it would quiet my mind) AND IT CAME BACK POSITIVE. I AM SITTING IN MY OFFICE AT WORK AT 2AM BY MYSELF AND CRYING MY EYES OUT BECAUSE I WAS NOT EXPECTING THIS!
