I Had Unprotected Sex On The 4th And I Took

I had unprotected sex on the 4th and i took an emergency pill. Then, on the sixth i had unprotected sex but interrupted in the 6th and i didn't took the pill. Ever sicne i've been urinating with blood and pain. now i don't feel the pain but i am bleeding way more. It is not possible that i am menstruating cause i finished it in the 4th. Do you know what could this be?
