The discharge you have is probably due to a hormonal disturbance causing breakthrough as happens occasionally during the normal pattern. It could also be due to local lesions like vaginitis
, cervical erosions and polyps. Implantation
bleed is a possibility at this time of the cycle but it is a fresh bleed. You should see a specialist to assess you properly and exclude organic causes for the spotting. You may have a serum beta-hCG measurement now as that is the earliest way to confirm/exclude pregnancy
. Hope this information is useful. Take care.
