What you are feeling might be the cyst they found especially if it is fluid filled. Definitely see a gyn and take all other info with a grain of salt for now since all this data is coming from people that are not experts on gyn issues. An ultrasound exam may find the missing ovary. Maybe inflammation from seat belt trauma is distorting images. Doctors really get it wrong sometimes. I hope all your injuries heal fully and that you get better information from a gynecologist. Best wishes!
Wow! So sorry to hear about your car wreck! If you have never had abdominal surgery...that seems suspect to me. It is possible to be born with only one ovary, but with it showing remants...that seems really strange! A MRI shows ovarian tissue better so you may want to request one. Perhaps your gyn will have more insight into this matter. Personally, I have never heard of an ovary being ripped away. Yikes...the thought of it is chilling! I am glad you are OK. Good luck to you!
