To test or not to test

Lindsay • Baby #4 on the way!
Today is it, D-Day. Evil AF was due this morning. Either she missed her flight and is running a little late, or I have a tiny baby seed keeping her away. I tested at 11dpo and got a BFN. I'm to scared to test again, but I really want to know. It's kinda a big deal I guess. Anyone experience a BFN at 11/12dpo and still get a BFP
