After birth complications PLEASE HELP

Jasmine

So I gave birth 3 days ago. Every since a couple hours after I had the baby I’ve been had this very bad cramping pain. They really feel like contractions to be honest. They are coming in waves like normal contractions as well. I’m the hospital they were giving me Percocets and ibuprofen 800 mg all the medicine did was put me to sleep it did not stop the cramps. Now I’m home and I’m still having the same problem. I’m taking the ibuprofen 800 but still nothing is helping. I’m not passing any clots and I’m not even bleeding heavily. What could this be? Is it the normal after birth pains or did they leave some inside me?
