If it wasn't too long ago you might still have pregnancy hormones in you and that would show in a blood- or urine test (as positive for pregnancy). if that has passed and you didn't see a doctor afterwards there is no proof. Otherwise you could have asked the Doctor Who examined you and maybe performed a D&C on you to explain.
Be true to your own heart and if you are truly not lying or cheating then realize she has the problem. Good communication skills are necessary to have a strong relationship so quietly sit down (without blaming your fiance) and ask why she thinks you are lying and cheating. She may have been cheated on once or more in her past; perhaps one or both of her parents cheated on each other so she is insecure and thus, she considers if you are not cheating or lying to her now you will be. If she continues to accuse you of lying and cheating after you have talked with her suggest she get psychological help and if she refuses which is a high possibility then you will have to decide if she is worth being with. You deserve much more than to have a relationship where your fiance and perhaps if you get married a spouse that is jealous and constantly accusing you of lying and cheating. You will know if your fiance will change or try to change and if not, then walk away because that means you have not met the right person in your life and they will be there in your future if you continue on in your life without your present fiance.
Prove to him that you aren't.
No, she is lying yo you and does not care if you know about it.
No there isn't but it's important the doctor know these things.
Candidate?
The best thing to do is to talk to them about it in person, dont accuse them if you have no proof yet, just ask and usually you can tell if they are lying. :)
Have them sit down and talk to you face to face.
