Any test is conclusive after 3 months and if hers was a duo it was also conclusive at 28 days. You are safe.
I'm the on who tested at two weeks
Then a month later and then at 81 days all came back negative, don't know what kind of hiv test they were I just asked for hiv test and they took out two tubes of blood all three times
She told me she was clean but I got tested anyways to make sure
I didn't want to rely on her status because she says she's negative I still wanted to make sure by getting tested just wondered if I'm in the clear or 81 days wasn't enough to be conclusive
