Dr. Hook,
I just test negative after 9 weeks. would you way that I'm in the clear now?
It sounds as though you are doing all the right things and thinking about this clearly, i.e. carefully considering your risks, working to avoid anxiety driven over-testing (it's hard) because of concerns regarding false positive tests, etc. Let's analyze your risk-
2 episodes of unprotected oral sex. Each exposure has an average risk of 1 in 10,000 if your partner was infected, this, if he was infected, your odds of infection are 1 in 5,000.
Your partner claims to be negative, thus he probably is.
You have a negative test at slightly more than 5 weeks at a time when 85-90% of all tests will be positive.
Putting all of this together, at this time I would put your chance of being infected at somewhere in the range of less than 1 in 100,000. Retesting at 8 weeks will increase those odds 10-fold ( to about 1 in a million). You have to decide if it is worthwhile. If the anxiety is getting to you I would either get tested yourself at 8 weeks or, better still, get your partner to test now. If he is negative, then you have no reason for further testing for this exposure. Either way your risk is tiny. Good luck. EWH
