Implantation?

Question please help. I believe I'm 9-10 days dpo. I took an opk on 10/1 and was very positive so I'm not sure if it could have been a positive a day before. Yesterday I started of with very light brown almost tan brown discharge. When I wiped once I had mucous with brown (tmi) sorry. Today it continues when I wipe. Can any one tell me their implantation experience please!
