I will NOT get AF next Friday (11/10 as I pretty sure that's the day I'm due for her) the day we leave for our first anniversary trip... and I can test that morning. Thus, giving DH the awesome anniversary gift (11/13) of telling him we're preggers. Although, I'm pretty sure I would have a hard time holding that information in for 3 days!
That would be an awesome gift! Now that I think about it, I could feasibly give that same gift to DH but we have 4 months to go. I hope you can hold it in if you have to.
