Hello all. New to these boards but in need of help. I am 12 days late, taken several HPT and all say no. Im having back ache like my period is going to come but nothing shows up. :( I have been pretty regular these last two years as I have been tracking my periods so I know I'm way past late. Has this happened to any one else? Can I be pregnant and not be able to have it read on a test? Anyone else have any of these syptoms? And actually be pregnant? Am I nuts and looking into it too much. I mean how late into a cycle can you actually be and have it registered on an HPT? Any help would be helpful. Its not the end of the world and my fiancé is very supportive either way it goes. Im just going nuts as to what the heck is going on with me... Help... Please... :confused:
