Period is officially late!

Okay so I have officially gone through the entire day and AF has not shown her face! My period since coming off birth control has been every 30 days on the spot! I refrained all day from testing scared she may show her face late at night but so far nothing! This is our 4th month TTC and I'm hoping tomorrow morning I get my BFP with first morning urine!! eeeeek! so excited! please send baby dust! on a separate note, how did you tell your So's you were officially expecting??
