If you had sex with a gril without condom there is always a chance that you may catch AIDS
if she is infected. Never act in such reckless manner in future. It is your life to spoil or savour. She has history of abortion
before ten years which is not very important for diagnosis. Does she have multiple sex partners apart from you that is does she have high-risk behaviour?
As You had unprotected sex you may get yourself checked at government centres where free check-up of AIDS is done. This can be done at three months interval for next three years.
