Can I Press Charges Against My Gynecologist?

Location: Pennsylvania I know the laws vary from state to state but given what happened to me I have no idea what to do. A few weeks ago I was being seen by a UroGyncologist I was referred to after experiencing recurring uti symptoms for a long time. She told me to undress as she was going to do a vagina exam, much like ones I’ve had done to me before (this was completely normal in my eyes). Things took a DRASTIC turn when a few moments into the exam this Dr asks me if I am constipated and I Replied that I wasn’t sure. After that, she then proceeded to shove her finger up my rectum WITHOUT TELLING ME BEFOREHAND WHAT SHE WAS GOING TO DO!!! I then yelled out in pain and pulled away from her immediately and she stopped what she was doing. Not only did this traumatize me as it was a massive violation of my body, but I’ve also been in a lot of pain ever since she did that. I’ve been seen by my PCP who said there is a small injury down there and I’ve been taking medication to help with that. I have multiple women in my family of all ages who all agree that what she did was assault because they’ve never had an experience like that. However, the office she works at is trying to tell me what she did was perfectly fine as she was performing a pelvic exam and a rectal exam is technically part of that. However, nowhere in her notes or the after visit summary does it say ANYTHING about her doing a rectal exam or the fact that she believed me to be “constipated”. My main questions here are 1, is what she did acceptable in terms of care and 2, am I or am I NOT allowed to tell my doctors what care I would and would not like to receive? Because if she had told me beforehand she wanted to do that exam, I would’ve 100% said no because I would not have been comfortable. I already reported her to the police, but I just don’t know where to go from here
