Sharp pain - 4 weeks 4 days c section

I had this and i had to go back to the gp who referred me for an ultrasound which showed fluid on my scar internally.
I had also passed a clot 12 weeks later which was remaining tissues; after this had passed the pain had gone.
I would go back to your gp to get checked

I went back at 9 week pp as i kept getting sharp pains and from my belly button down was sensitive to touch. Which they sent an urgent referral through to check if there was any infection or anything remaining which took 4 weeks but then i passed a skin colour clot which the gp said it was remaining tissue.
