Fingers crossed this results in a BFP for you hun. With my last pregnancy mine was showing -ive when I was in fact 5 weeks pregnant. I know mine ended badly, but this has nothing to do with why it did not show at 5 weeks pregnant. At 9 weeks pregnant I had a Blood Test and my HCG levels were through the roof, so I assume they were at 5 weeks too but for some unknown reason just decided not to appear as a BFP. I was told that some women a re just like this. Also in saying that, there is a chance you are just having a longer than usual cycle, as some preg symptoms are the same as AF symptoms. I am 13 weeks pregnant, and still have no symptoms so who knows how it all works, but Best of Luck xx
