Okay. Can 7 pregnancy tests all be wrong?? I think not. I'm not sure when my period is actually due I can only assume Monday to today. I have all the pregnancy symptoms. I got a very faint positive 6 days ago (first response) but all the others are saying no. I'm not trying to have a baby but I know my body and I have 2 kids. I feel sick. My boobs hurt. I'm tired. I have headaches. I've gone off food. And I had unprotected sex on a 'fertile day' so if I was surely by now id show up pregnant?? Is there any other explanation? Other than I'm nuts?
