Bleeding/spotting after delivery

NSVD, 1 month PP, EBF. Mga mi hanggang kailan kayo merong spotting/bleeding? Sa case ko kasi until now may brown discharge ako. Madalas onti na lang, minsan madami, may times na may kasamang blood. Normal lang ba? Kayo ba? Or should I be worried? #firsttimemom #pleasehelp #FTM
