protected sex = NO risk.
testing is not needed.
I'm not sure what you mean by wearing two condoms and then a third. If you mean that you wore three condoms at the same time, you really shouldn't do that (and there isn't a need to). It can make the latex rip more easily. So if you could explain what you meant, that may help.
If you use condoms correctly and consistently during intercourse, you will not contract HIV.
