TMI PHOTO! Chunk of mucus 2 months after c-section

What is this? I know it's mucus but it's super thick and a lot of it. I'm 10 weeks post c-section. Never actually went into labor but had lost some things Iike this a couple of weeks before having the baby. Could it be parts of mucus plug still coming out? I had a 2 day period last month, very light but DR said it was a period. I'm so confused. 😩
