False positive


I was always told that getting a false positive is likely to never happen. Well, leave it to me to experience it. I tested four times over the weekend and they were all positive. This morning I woke up and had started bleeding. I went to the doctor, and got a blood test done, and the results were negative. The nurse told me I had never been pregnant because I had no sign of HCG hormone. She said I got a batch of old tests or something went wrong when testing. I have no idea what could go wrong during testing, but there ya go...false positive. So heres to me starting my period 7 days late🙁
