How can I make this more realistic - what would actually happen?

Hi, I'm writing a book and trying to get some information that will help me write a bit of it.

My main character faints while in hospital visiting a friend and wakes up in a hospital bed. She will find out that she is pregnant. A few weeks before this she was violently raped (resulting in the pregnancy). But i've relised that this isn't a very realistic scenario. I could just make it that she suspects it herself, and does a pregnancy test then goes to the doctors to make sure?

The thing is, she was drunk and drugged and has no memory of being raped, so i need her to be told that she was raped, or at least that (from the tearing and bruising) it was a possibility. So how could this happen?

I was going to make it that the doctor (a female) examined her genitals and saw the tearing and bruising from the rape, which would result in awkward conversation where the doctor gently asks if she has been sexually abused. But would a doctor even be looking down there even if the patient was pregnant? Would she be checking that everything was fine with the pregnancy since it would be very early or what?

Thanks for your help, any information would be appreciated.
