Spotting

I'm 4 months postpartum nd i have pelvic bone soreness and abdominal discomfort yesterday I started spotting brown like this I dont have periods due to breastfeeding nd was curious if this type of spotting is normal. I did have a hernia left unresolved after birth wondering if that's the cause or if this is just normal spotting. It started has some faint light brown spotring has kinda evolved into more.
