You never has a risk. You used a condom, it is an effective barrier to HIV transmission. You didnt need any testing.
I suggest you to seek assistance for your anxiety. I feel, for a lot of people with no risk scenarios 2 major emotion starts prevailing post sex - guilt and doubt which futher leads to anxiety, ocd, paranoia.
Mind is very powerful, it starts releasing chemicals that makes you believe that you have contracted the virus. You visualise every thing that you read online, also the body syncs in with the mind, body starts exhibiting things that mind percieves. Then comes the testing chronology - You keep testing obsessively, starts questioning late sero conversion. The whole thing is is viscious cycle. It's a trap that you put yourself in. The main culprit is the internet, you keep accesing information that has varied point of view and constantly relate it to your own self.
Save your self from the trouble, rationalise and accept, you were protected and HIV is not your problem.
