I am now 40 days late, I have taken test & all were neg. My peroids are sometimes off by a week at the most, never this long. I have been trying to concieve for over 2 years now. So I am hopeful that I could be pregnant- but with all the neg test I doubt I am. I have no other symptoms of being pregnant accept wanting to get pregnant. What else could be wrong with me? Please help Im going crazy here.
