OK so I did a test this morning with a boots test I managed to find, which I subsequently realised was over a year out of date 
.Anyway, it came up with a positive pink line almost immediately, which was still there after a couple of minutes but had disappeared not long after.
I will obviously go and get an in date test but does anyone have thoughts on whether this might be accurate? I can't get out for a new test for a while and am bamboozled.
