thanks for replies everyone
my problem is this - i've had it before and was treated and re-checked for everything and given the all clear - my dp was treated too.
i remained totally faithful , up intil a few months ago when i was very silly i regreted it before the deed was even finished and stopped it there and then - the other person say's he's sure he's clear as was tested not too long ago and been with the same dp since.
could the result - inconclusive - be some echo of my previous infection?
