Bleeding while taking Daphne

Anyone here taking Daphne after giving birth? I took Daphne 2 mos aftr i gave birth may konting breastmilk pa ko when i started the pill then after 10 dys nag spotting na ko until today medyo malakas na ung bleeding di na kaya ng pantyliner lng. Breakthrough spotting pa ba yun or period ko na talaga? Alam ko i shud not have my period until i finish the 28 pills... anyone here hu experience the same?
