Hi all, decided to join after a lot of lurking on this forum! Yesterday I took a clear blue plus test and a faint line appeared after about a minute. As it was quite faint I couldn't be sure of the colour of the line, so I dipped another test into the same pot of pee. Again, a line appeared but very very faint, more faint than the other test. They didn't convince me so today I have done a digital test and a first response test and they both came back negative. I looked again at the tests from yesterday, as I've kept hold of them, and one of them the line has got darker and is definitely blue in colour. Surely that isn't right! I'm rather confused.... has anyone had similar experiences with these clearblue plus tests? Surely I couldn't get 2 evaporation lines straight after each other? but then the other tests did come back negative??!
