Light brown watery discharge instead of a monthly period

Hello po, sana po may mga nkakaalam po nito na mga mommies. LMP ko po is July 11-15 po then may nangyari po sa amin ng partner ko July 26. So ngayong August po, may discharge po ako na sobrang light brown po at kunti lang po sya, bale August 20-22 to be exact na puro watery na light brown yung discharge ko. Is this implantation bleeding po ba or other concerns na dapat kong ikabahala? Please enlighten me po. Thank you. #pleasehelp #advicepls
