My exposure was unprotected sex with a female of unknown status, I tested using oraquick home swab 5 times, 5 weeks negative, 7 weeks negative and 11weeks negative so after about 15 weeks post exposure I took two oraquick swabs at the same time both were weakly reactive the t line was so faint I had to get under light to really see it and as time pass like a hour or so, the control line got very dark and the t line was still very very faint, i usually keep them for a hour a so just because I know after a while the lines get darker but the t line didnt I mean it's so faint that I think my eyes are playing tricks on me but my question is, how can someone test positive (weakly reactive) at 15 weeks twice at the sometime but I tested negative at 5,7 and 11 weeks I dont know what too believe can somebody please help me please.
