Yellow/ orange discharge since 7dpo

And today is now 9dpo. I got checked out because I thought it could be an infection and doctors said its not. I didn't want to take a blood pregnancy test just yet when I was there. Doctor didn't give me much info. But cod this be from implantation. Anybody expierence this discharge and got a positive hpt? I know cm isn't a good indicator but I have NEVER GOT this type of discharge before
