Two nights ago I took a pregnacy test and even though one of the lines was more faded than the other one, I was told that it was still a positive. Just to make sure I took another one the next morning with the same results. I went to a walk-in clinic and told the doctor about the tests and he said that I was pregnant, but when I did one of there pregnancy tests(ndifferent from the ones I took) the results showed up negative, so I got a blood test done and find out soon. I just want to know how it's possible to have two posistive pregnancy tests and then a negative one.
