Well this morning was a definate negative..... but its actually less sensitive than than the one that gave us 2 positives...

So I'm going with negative, but Ad isn't convinced.. hhhhmmmm, that say's a lot!!!

So I've had;
invalid
negative, at night, that went positive after 10 min
positive FMU
negative, in arvo, positive after 10 min again
