A broken condom is a one time sex exposure and is, therefore, really low risk. The statistic is less than 1 percent transmission rate from a on time exposure. The odds are in your favor most assuredly. Since it is a 3rd generation test, it's going to be conclusive at 90 days. I would not be very worried but repeat the retest the. Remember, LOW RISK from a one time condom break.
I think the Tridot test is not a duo so you have to wait for 3 months to test. If she always uses a condom, then it is to protect herself from customers and she would likely be negative anyway otherwise why would she spend money on condoms? I would test at 3 months, but would not worry while waiting since she is probably negative.
