I have delivered a baby boy 20 days ago via normal delivery. Every thing was fine but immediately after delivery i faced severe shivering for almost 2 hours and then excessive blood loss. It was too much that doctor put some pads inside me and removed them the next day. They came out and doctor said now u r fine. I want to know what could be the reason for that much blood loss?? At the time when doctor was treating me she said tmhara uterus bhi contract hogaya hai bleeding honi to nhi chahiye but when she removed them the next day she said uterus contract nhi hua tha tmhara. Please guide me what could be the reason? Is there anything to worry about??
