I received a bj several months ago and became terrified of the prospect of getting hiv. So after the fact I purchased several oral swab kits. One of my initial tests at the 6week mark terrified me. It was negative until a small thin line appeared on the left hand side after 30 minutes of being non reactive. I followed up with a test the next day that came out negative. Took an Orasure at 9 weeks, 11, and 13 all negative. Any thoughts on this matter? Should I worry going forward?
