I put off using it for a few months!
The self test kit arrived very quickly, but I put off using it for a few months! Result: negative. It was nice to be able to complete the test in the privacy of my own home in my own time. Really easy to use with very clear instructions. I agree with the other person’s comments here though: the packaging/documentation seems like the most expensive part of the kit! Having said that, I feel it was money well spent in my case. Very good kit.
