Confused 😭😭

last mens ko po is Jan 22-28. then nag do po kami 2 days after ko magkaroon. Last Feb 11-13 po is may kaunting Dark-Light Brownish discharge po ako. 20 days na po after ng period ko ‘yun. Possible po ba na spotting ‘yon due to implantation? or false menstruation po? nag-pt po kasi ako pero nagative po ‘yung lumabas.
