AF is now 25 days late, with no obvious signs of showing up. I am having symptoms, but they are not my regular period symptoms. They are more like pregnancy symptoms. I have taken quite a few tests that all show up negative, and I know it sounds stupid, but I just don't feel like I normally do when my period is on its way. My aunt made me an appointment to get a blood test done on Wednesday. Is it even possible I could be pregnant even though nothing is showing up on home tests? I dont want to get my hopes up.
