I had a C-section too, mummy ❤️ My lochia lasted around 4–6 weeks, and I still had red bleeding on and off during the first few weeks. My doctor told me that day 15 can still be normal, especially if the flow isn't getting heavier. Just keep an eye out for very heavy bleeding, large clots, bad smell, or fever. If any of those happen, I'd get checked 😊
