Went to the doctors two days ago got blood and pregnancy test came up positive but it was very low it was just a hair above the cut off to be negative it was 1.8 to be postive it has to be 1.5 my doctor said... went back today to see if my levels were rising and they were 2.4 but doctor said I'm not pregnant now and not to go in for anymore blood work I'm confuse they went up but now I'm not pregnant?
