@guss I sounds like you do not trust what she is saying and she is confused and/or doesn't understand or want to share the information with you. We don't know at this point. I'm not see this scenario turning out well without those key ingredients of honest communication and trust. This is only my opinion coming from my own experiences. Have you considered sitting down with her and talking this out? I think people often makes things overly complicated by not being direct. Of course we should be kind too during this process. Could you ask her if you could help figure this out so you can both find the best way forward? Most medical notes are now available online and through apps. You should be able to easily read those notes. She may not want to share those notes with you and that is certainly her right.

@guss- I agree with @erikas. She has changed her story three times now. I don't know how old you are and it sounds as if you haven't been with her that long. Just make sure that you have protected yourself and go with your instincts. Usually they are right!
