Which result is valid?
I did a test yesterday morning and after 15 minutes it came out negative. It stayed that way for the rest of the day until I put the tube in my handbag so I could go out and bin it. When I took it out to double check it was there, I stupidly looked at it again even though I know I’m not supposed to look at it after 1 hour. When I looked at it I could see that my blood was spilling everywhere on the test as I was moving my bag around a lot. The next morning I woke up to a very faint second red line even though it definitely wasn’t there yesterday. Should I be concerned? Is my negative result the one I should stick with? Last possible exposure was a low risk activity just over 2 years ago.
