painful sex

Has any one else gone through this? 
I'm 11 weeks PP and I had sex once last week and tonight. 
I feel tighter than I ever felt like WORSER than when I was a virgin
 it feels like my vagina burns with condom 
feel swollen inside like my uterus is low 
And right after we are done I bleed a lot 
I'm scared I must have gotten hurt while giving labor i did get stitches 
But I hope my vagina goes back to normal or if I should make it a case I'm planning to make an appointment tomorrow for next week
