I went to the doc today cos if you look at my ticker i'm on day 40, 19 DPO and no AF she did the pee test and she said there was a faint second line but it's not where it should be, she compared it to the diagram on the packet and said she didn't know how this one worked. I'm a little confused how many lines can show up on a test? it was well and truly within the time frame and came up pretty quickly. I had a blood test too so that should confirm it. Has anyone heard of this?
