Missed period & BFN??

Jessie Rae • Owner of 2 gorgeous Siberian huskys☺️ have the best SO I could ask for and TTC #1
My period was due 7/8 and it was a no show.. I am always on time.. But first response tests show BFN ); I had 2 days of brown red discharge, small quarter amount that I wiped away and that was all for the day...
My mother said she never popped positive until after 2 weeks of missed period... Anyone else??
