Typical light bleeding before period

Hi ladies! Since I’ve been off BC, I usually get a day or two of “Pre-period” discharge. Brown or light pink discharge, followed by a short (bloody) period for a few days. My husband & I have been TTC for almost a year and a half. The first few months, I thought this discharge was implantation bleeding...but over a year in, I realize it’s not, as it’s always followed by a BFN and a period. My question is - does anybody else get this, and if so...if you’ve ever conceived...did you also get the discharge the month you conceived? I’m usually right on time, but I’m currently five days late, getting negative HPTs, and just started getting the Pre-discharge. God I just want to be pregnant!!!
