So I have poas every day since but I only have those cheap One Step tests from Amazon, which claim to be 10miu, but they have all been completely blank. No line. Nothing. So, I'm not sure whether I have imagined seeing what I thought I saw in the above test or these ICs are just rubbish. I have felt like rubbish since I did the test, which is why I did it. Perhaps it's just a cold, it's just no one else in the house has a cold... perhaps I'm just lucky lol
