I'm not really sure what your follow up question was getting at but your last test, a duo at 31 days was fully conclusive. At this point, after a genuine risk of broken condom, you did the responsible thing and got tested. You tested negative in the appropriate time frame so would not try to remove this situation from your worry well. It is over and you didn't get HIV from it. It is harder to get HIV than most think and a broken condom is less than a one percent chance of someone getting HIV from that one time situation. So, I am not at all surprised you are negative. Take care.
