WHAT IS THIS ON MY C SECTION SCAR??? TMI WARNING ⚠️

Clo

So last week i was on my period and noticed some blood stains on my underwear and pajamas right around the band. I didn’t think anything of it because I was on my period and blood just ends up everywhere. I believe that was about 4-5 days ago. Last night I noticed more blood on my underwear and I checked my c section scar and this was there. I did call my doctor earlier today but I’m still waiting for a call back. Has this happened to anyone? Anyone know what this is?
