How to tell my husband...

LJ • Baby girl born Feb 19, 2015 and second girl born Jan 20, 2017. Baby #3 due in October!
I'm either 11/12 DPO and got the most beautiful second line on the FRER. Tested a couple of days ago and no hint of a line. My husband comes home on Friday, I need some ideas on how to tell him. Any thoughts?  Also, if I took a weeks predictor test tomorrow would it be positive or should I wait?
