I am currently trying to conceive. I have had sex all different things throughout April, and my husband ejaculated in me every time. I am currently 9 days late for my due period, but I'm only getting negative results on pregnancy tests. However, I have no signs that my period will start, and have been having some early pregnancy symptoms such as headaches, backaches, moodiness, exhaustion, and constipation. I have read of women getting abnormally late positive tests, some even being 4 months along before a test is positive. I'm wondering though, how common a late positive is? Or if my period, which is never THIS late, is just late.
