When did your bleeding stop?

Hello - I know this question has been asked a lot, but when did your bleeding stop? I had a very smooth c section delivery and was able to walk a lot already beginning day 4. Even though I was walking a lot the blood gradually went away to the point where it was just white lochia. However, I made a mistake and did too intense of exercise around week 4 and the bleeding returned heavily (e.g. blood when I peed in the toilet, clots, blood in the pad, but I usually changed the pad 3 times in a day it wasn't dangerously soaking my pads or anything). I messaged my OB and told him it started up after exercise but he said that was my period. I wasn't so sure though. It could have been, but I didn't feel what I thought was any cramping. It did have the musty smell kind of though like period. It gradually went away once I went back to just walking again. However, I've just been walking for the last 2 weeks, it went away, and then it started back up 2 days ago. I don't know what to do because all I can think of is that it's from engaging my core muscles too much from lifting my baby. I miss the gym and I am so frustrated. I still don't regret getting a c section given the vaginal birth was not an optino for me no mat ter what, and my baby was delivered safely. I have no pain at c section site or in my uterus. Anyways, when were you able to return to like jogging and regular exercise again without the bleeding starting up again? I just hope this doesn't take another 10 weeks to fully go away ughhh. I am also concerned it could be retained placenta or something but I wouldn't think my doctor would make such a mistake - he was a very good surgeon and my recovery was so so easy. I didn't even feel like I had a c section after just a few days. ChatGPT told me with retained placenta you usually don't bleed after just exertion but usually continuously, so that gave me some reassurance. I wasn't going to go in and check for retained placenta unless I was still bleeding past 16 weeks off and on. I can't even tell what's lochia and what's my period too! Ever since my pregnancy my vagina is very very sore not sure why and I can't even have sex. I think it's my pelvic floor I think I am getting closer to being able to put a tampon in again but the point is a wand going up my vagina to dot he ultrasound to check for retained placenta IDK if I can do it right now. And I don't think I should try putting a tampon in while I'm bleeding still. It dissapeared after I rested fro the overexertion, but I guess my baby getting bigger makes me engage my core when I'm picking her up each time.
