Question !

Yari ❤ • TTC For Baby #2 Have A Beautiful Lil Boy Hoping For a Beautiful Lil Girl(:
So I had brown discharge (what thought was IB ) . For 9 days (Sometimes just when wiped) I started spotting June 11 till June 20 . AF was suppose to show June 26 but still nothing. I took 2 HPT and both negative . (Took them 4 days late and other one 1 week late ) my question is if I got 2 negative HPT does it mean it wasn't IB when I was spotting ??? Please someone help .
