C section is it infected or really irritated?

4 weeks pp was really bruised after section that has mostly went away. My scar isn’t bleeding or feel overly painful. It also doesn’t feel like there is any lumps or fluid build up underneath. The photos look much redder than it actually is and makes the area look a lot larger. Just looking for a bit advice baby is in neonatal and it’s difficult trying to look after her and myself. My stomach hangs over my scar and tend to sweat often wondering if this is causing irritation. Can anyone help?
