Participating in Martial Arts with Factor V

I have factor 5, my daughter takes Xarelto because she has Factor 5 as well. She had two pulmonary embolism go through her heart,and into her lungs. Why she is alive we don't know how,I'm am so grateful she is,however the doctor said usually people won't live through that. So I was tested,and the Factor 5 came from me. I have never had a blood clot so the doctors didn't give me blood thinners. The rule of thumb Is from what the doctors say is no blood clots or issues,they won't give blood thinners to you,even though you ha e Factor 5. I went to the doctor and he freaked because I had not been taking blood thinners all along. Does this sound right? I look at it as I don't want to wait until I have a clot before i deal with it. I'm 53 I smoke. I may not get a chance to deal with it and die. I'm taking Warrfarin. Not sure if it's the way it should be anyone know?

I lived a very normal life and still do and I wasn't diagnosed till last year.
