Hi Doc, mine was csection delivery(first baby). I had my postpartum bleeding for 28days. After 2 weeks I had my periods which lasted for 4 days. Within a week, I had my periods again. I checked with doctor, she said its due to hormonal imbalance and told me to take Primolut N for 3 weeks course. 3 days after the course got over, my periods started. For the past 2 days, Im having heavy bleeding. Im really worried, it might be due to the tablet? I had regular periods and no problem before delivery.
