I'm confused! TMI

I was supposed to start my AF on the 2nd of June, my AF Is usually heavy and always on time, always lasts 5 days. I got some light pink blood on the 2nd followed by some brown, usually with AF I have to change my tampon, 5/6 times a day, this time only had to have one in for a few hours. It's been going on for 6 days now, light pink and brown, very light barely comes out it's just sitting near my cervix, occasional darker red, I've gotten 6 faint very faint lines on HPTs and it's not a miscarriage or eptopic. What's going on?
