I went to my local NHS GUM at 3 weeks
for advice (not knowning the window periods.I wonder if the nurse also did
for she decided ti to test me at 24 days (this to the best of my knowledge was a 4th GEN).
I had to wait 2 weeks for my results and after a VERY stressful fortnight, they came back negative. Relieved, at week six I got a very dry mouth. Concerned, I phoned up the GUM clinic again, there a health adviser told me the nurse had got the timing wrong and it should have been 28 days.
