*Tmi sorry in advance*

I'm 2weeks PP and today I had two big clumps when i went bathroom. Is that normal? Bleeding is minimal and light just got spooked when went to flush toilet and noticed a big clump. I had stitches after birth and its uncomfortable trying to sit or lay with a pad on. Switched to ultra thin pads to help and also been using witch hazel pads and a spray. I dont have my pp appointment for another 3 weeks😥 any advice and is random clumping normal? First time mom*
