Sorry to heard that OP, you said No and she didn't heard it/respect it, you should really report it, and even more if you are not sure if she took off the condom, you never know if she will later get pregnant and then use it to her favor and don't forget get tested.
And don't feel ashamed or angry about yourself, try to find help with a therapist or a really close friend / familiar , I can't imagine how vulnerable you must feel.
