Big blood clot 4 ;days after birth

Hi all, what would you do in regards to this? Had baby 4 days ago and just passed this as felt it coming out so went to the toilet.

I had retained placenta after giving birth to my first so just worried. I feel fine in myself and am breastfeeding so hoping this helps with getting rid of anything from my body.
