discharge (tmi)

Courtney
Brown discharge that won't go away it's been over a week now and I'm wondering if this could be implantation bleeding or something it's not heavy just when I wipe and not much and sometimes not at all thought it stopped yesterday but I've had some on the to when I wiped today also boobs have been sore for the same amount of time no sickness or anything but opinions on this AF due July 2nd
