Shall I also file I claim with her insurance company and am I at any risk?

Collision resulted in minor car damages for both parts. According to the police, in our case and because collision was in a private property it is a "no fault" situation. Other person filed a claim with my insurance and lied saying she was injured. She had mentioned she was 10 weeks pregnant so I insisted she should be checked. So police had the firefighters come and check on her. She was fine with all vital signs normal and she refused to go to a hospital stating she was fine. I have the police report and it states all the above. I have never had involved in any car accidents and have no idea if with such a minor thing I should seek help. Thank you!
