Is this normal or should I get checked out?

bl

I'm 12 days pp. Had my son via c section. This is my first but my mom had a c section 34 years ago ( my brother) and she says it's normal. I'm starting to think something is wrong. I'm sore in this spot where the lump is. My incision don't hurt and healed pretty quick. It hurts to cough laugh get up sit down and some times pee. I'm also having brownish discharge and I bleed here and there some times pink others red. I stopped bleeding while I was at hospital but started again after I got home. I can also leave impressions of my fingers in this spot with just a light touch. Iv lost my belly up top but not down low because of this. It makes me look huge when I'm not that big. I am over weight but not this huge.

My incision after Staples have been taken out.
