I just gave birth 2 months ago, my husband wanted to have sexual Intercourse but we couldnt , it was very painful and it feels like if I had a wall in the enttance of the vaginal part that didn't let him put it in, I grabbed a mirror to see if I had something weird and it seemed like something pinkish like of it was tissue or something in their and i have bleeding spots Like brownish with a smelly odor what could it be?
