Implementation bleeding ?or early af ??

DEANNA
Yesterday at 9po I had dark brown spotting with huge cramps ..this morning heavier bleeding but not enough to reach pad only when I wipe it's medium to heavy. Still cramping (awwh) I'm five days early from af .in 2012 I was pregnant with twins had what I thought was a period and bled off and on after that .found out I was 16 weeks pregnant when I went in for an exam after cancer surgery .. (lost them due to treatment ) .anyways I guess what I'm saying is has anyone had heavy implementation bleeding and still got bpf. .I'm never early either! Feel like ground hog day all over again. ..
