4weeks PP

I need some advice, I’m a first time mom and I’m 4 weeks postpartum and I’ve noticed an odour (very tmi) that is kind of fishy but smells like a dead animal 🤢 I’ve taken good care of my hygiene, staying hydrated, haven’t had s*x either. I don’t have any itching or burning or anything. So I don’t think it would be an infection.
