My period is late by 11 days so far, my doctor did a blood test on the second missed day and it was negative. She then sent me for an ultrasound for reasons I still don't know. I had the ultrasound done today but the tech said she is not allowed to say if I am pregnant or not but then she continued by saying if I were I would only be around 5 weeks and it would too early to see anything which I take means I am not pregnant because she obviously saw nothing. My doctor told me to take another test in a week. I feel pregnant, the tests are saying I am not pregnant and my doctor keeps telling me to test again and I am finding it frustrating because she is giving me hope that the tests keep taking away. Is it possible the test are wrong?
