Septic vs growth lines

[Shann1422]

Please help my 3 year old female Hermann i noticed her belly pink tinged after soaking today. Not sure if it’s just staining from substrate or if it’s shell rot or sepsis? Or something else? Please help. Pics with and without flash. Am i overthinking???

Looks perfectly normal to me

Looks normal to me too. The pink is likely blood supply that is feeding new plastron growth.
