OMG.....I am in total shock!

So AF is now 5 days late so I decided to take a test since that past couple mornings I have woke up sick and vomiting. I am in total shock cause due to my husband's work schedule we were unable to baby dust during my fertile window, but baby dusted a couple days before. I'm overwhelmed with emotions right now cause I am so shocked it happened. I did accidentally drop the test, could that cause it to be positive? I am unsure if this is something I should share with my husband right away.
