I Had An Abortion At 13 Weeks Last Friday. It

I had an abortion at 13 weeks last Friday. It followed with complications and I ended up losing 6 liters of blood and having to have a c section due to there being a tear in my cervix. I'm still very swollen in my stomach, more than I was even when 13 weeks pregnant and I'm wondering how long it will take for it to flatten? First c section I've ever had. 3rd pregnancy, I had my other 2 children vaginally and within 4 weeks i was back to my old self and flat stomach. I barely gained 10 pounds this time so I'm confused as to why I look more pregnant after..
