Postpartum bleeding

EBF po ako, normal lang po ba nag stop na ung postpartum bleeding tapos bumalik ulit? 7-10 days po ako deretchong dinugo, after nyan pasulpot sulpot nalang. Then mga 3rd week after giving birth, brown and yellow discharge nalang. Ika-4th week, dark red and malakas na bleeding nanaman, ngayon light red na pero malakas pa rin ung pagdudugo. Is this normal po?
