Can I a hospital for leaving remains in my uterus?

I had a miscarriage in January and i went to the hospital twice once when they told me i was having a miscarriage and after i passed everything, the hospital did a ultra-sound and they said every had passed out. I could not work for a week, because of the amount of pain I was in, they didn't give me anything to help me pass they fetus or placenta. I wasn't given any papers regarding the fetus i gave them on my visit i wasn't mailed anything, they took my fetus and all I retrieved was expensive medical bills after.Flash forward to March i had been bleeding all month and i told my doctor about the bleeding and he ordered me to have an ultra- sound done. My doctor told me that there were remains of blood and issue in my uterus from the miscarriage. My doctor told me they should have done a D&C when they saw i was having a miscarriage. He admitted me to the emergency room that day to have an D&C. 4 hours later the ER doctor said that he didn't want me to have the D&C because he didn't want to put my body through extra stress. I still need too have a D&C which is a surgery. I missed a week of work because of the hospital visit.
