4 weeks post c section - pain appeared

4 weeks exactly post my 2nd c section, and recovery had been great. Off pain killers etc since 10 days pp, and moving around pretty freely. I took stool softeners in hospital with pain meds, and had no issues or pain with BM. Randomly 3 days ago I had a BM and had a sharp, stabbing pain just before and during. The pain was in my abdomen in the c section area. Since then, I’ve had worsening c section pain, and it’s reminding me of being a few days PP, not being able to stand up straight etc. strangely I’ve also felt some sharp pains in my bottom/bowel area. My abdomen feels much more bloated than it had. Has anyone experienced anything similar?? In hindsight I haven’t been taking it as easy as I should and I’m freaking out I’ve got internal damage and have to wait til Monday to ask OB
