Implantation bleeding or AF

pretty • Sat, Dec 08

I just went to the restroom and wiped I had brown discharge and light spotting that only showed when I wiped my af suppose to come on in 3 days could this be my af or implantation I also haven't had any cramping which I usually have just sore nipples and nausea but no throwing up but I got a BFN 12am on the 6 when I reached my 9 DPO mark but I think my hcg levels weren't high enough
