I had a brief "dipping" experience with someone of unknown status, but claimed to be clean almost 10 weeks ago. I have had virtually no symptoms except for a white coated tongue, which may be thrush, but doesn't look as bad as most of the pictures I have seen since searching pictures online. I have tested multiple times; 21 days - Oraquick, 30 days - Oraquick, 35 days - Oraquick, 38 days - 4th generation ag/ab duo test through MyLab Box, 42 days - Oraquick, 48 days - 4th generation ag/ab duo test through MyLab Box (for all STI's) & finally at 64 days - Oraquick. All tests came back negative. Would this be conclusive, as my concern is my tongue is still coated, but has no gotten worse. Thanks for any advice.
