Experiencing heavy bleeding 35 days after a C-section requires prompt medical evaluation. Please contact your obstetrician immediately rather than trying to self-medicate, as the correct treatment depends on the exact cause (such as retained tissue or a delayed recovery of the uterus). Your doctor may perform an ultrasound and might prescribe medications like uterotonics (such as methylergonovine) to help your uterus contract, or antibiotics if an infection is present. If you experience fever, severe abdominal pain, or pass very large clots, please seek emergency care. This is a highly treatable issue, so please reach out to your healthcare provider for safe, personalized guidance.
